PowerLogicTM Series 800 Power Meter Chapter 1—Introduction

Chapter 1—Introduction
This user guide explains how to operate and configure a PowerLogic? Series 800 Power Meter. Unless otherwise noted, the information contained in this manual refers to the following power meters:

? ? ?

Power meter with integrated display Power meter without a display Power meter with a remote display

Refer to “Power Meter Parts and Accessories” on page 5 for all models and model numbers. For a list of supported features, see “Features” on page 7. NOTE: The power meter units on the PM810, PM810U, and the PM810RD are functionally equivalent.

Topics Not Covered In This Manual
Some of the power meter’s advanced features, such as on-board data logs and alarm log files, can only be set up via the communications link using PowerLogic software. This power meter user guide describes these advanced features but does not explain how to set them up. For information on using these features, refer to your software’s online help or user guide.

What is a Power Meter?
A power meter is a multifunction, digital instrumentation, data acquisition and control device. It can replace a variety of meters, relays, transducers, and other components. This power meter is equipped with RS485 communications for integration into any power monitoring/control system and can be installed at multiple locations within a facility. These are true rms meters, capable of exceptionally accurate measurement of highly non-linear loads. A sophisticated sampling technique enables accurate measurements through the 63rd harmonic?. You can view over 50 metered values, plus minimum and maximum data, either from the display or remotely using software. Table 1–1 summarizes the readings available from the power meter.

Min/Max Values for Real-time Readings
When certain one-second real-time readings reach their highest or lowest value, the power meter saves the values in its non-volatile memory. These values are called the minimum and maximum (min/max) values. The power meter stores the min/max values for the current month and previous month. After the end of each month, the power meter moves the current month’s min/max values into the previous month’s register space and resets the current month’s min/max values. The current month’s min/max values can be reset manually at any time using the power meter display or PowerLogic software. After the min/max values are reset, the power meter records the date and time. The real-time readings evaluated are:

? ? ? ? ? ? ? ?

Min/Max Voltage L-L Min/Max Voltage L-N Min/Max Current Min/Max Voltage L-L, Unbalance Min/Max Voltage L-N, Unbalance Min/Max Total True Power Factor Min/Max Total Displacement Power Factor Min/Max Real Power Total

NOTE: Min/Max values for Vng and In are not available from the display. Use the display to read registers (see “Read and Write Registers” on page 26) or use PowerLogic software. For each min/max value listed above, the power meter records the following attributes:

? ? ?

Date/Time of minimum value Minimum value Phase of recorded minimum value

? ? ?

Date/Time of maximum value Maximum value Phase of recorded maximum value

NOTE: Phase of recorded min/max only applies to multi-phase quantities. NOTE: There are two ways to view the min/max values. 1- Use the power meter display to view the min/max values since the meter was last reset. 2- Use PowerLogic software to view a table with the instantaneous min/max values for the current and previous months.

Power Factor Min/Max Conventions
All running min/max values, except for power factor, are arithmetic minimum and maximum values. For example, the minimum phase A-B voltage is the lowest value in the range 0 to 1200 kV that has occurred since the min/max values were last reset. In contrast, because the power factor’s midpoint is unity (equal to one), the power factor min/max values are not true arithmetic minimums and maximums. Instead, the minimum value represents the measurement closest to -0 on a continuous scale for all real-time readings -0 to 1.00 to +0. The maximum value is the measurement closest to +0 on the same scale. Figure 4–1 shows the min/max values in a typical environment in which a positive power flow is assumed. In the figure, the minimum power factor is -0.7 (lagging) and the maximum is 0.8 (leading). Note that the minimum power factor need not be lagging, and the maximum power factor need not be leading. For example, if the power factor values ranged from -0.75 to -0.95, then the minimum power factor would be -0.75 (lagging) and the maximum power factor would be -0.95 (lagging). Both would be negative. Likewise, if the power factor ranged from +0.9 to +0.95, the minimum would be +0.95 (leading) and the maximum would be +0.90 (leading). Both would be positive in this case.

Demand Power Calculation Methods
Demand power is the energy accumulated during a specified period divided by the length of that period. How the power meter performs this calculation depends on the method you select. To be compatible with electric utility billing practices, the power meter provides the following types of demand power calculations:

? ? ?

Block Interval Demand Synchronized Demand Thermal Demand

The default demand calculation is set to sliding block with a 15 minute interval. You can set up any of the demand power calculation methods using PowerLogic software.

63230-500-225A2 3/2011

PowerLogicTM Series 800 Power Meter Chapter 4—Metering Capabilities

Block Interval Demand
In the block interval demand method, you select a “block” of time that the power meter uses for the demand calculation. You choose how the power meter handles that block of time (interval). Three different modes are possible:

?

Sliding Block. In the sliding block interval, you select an interval from 1 to 60 minutes (in 1-minute increments). If the interval is between 1 and 15 minutes, the demand calculation updates every 15 seconds. If the interval is between 16 and 60 minutes, the demand calculation updates every 60 seconds. The power meter displays the demand value for the last completed interval. Fixed Block. In the fixed block interval, you select an interval from 1 to 60 minutes (in 1-minute increments). The power meter calculates and updates the demand at the end of each interval. Rolling Block. In the rolling block interval, you select an interval and a sub-interval. The sub-interval must divide evenly into the interval. For example, you might set three 5-minute sub-intervals for a 15-minute interval. Demand is updated at each subinterval. The power meter displays the demand value for the last completed interval.

? ?

Figure 4–4 below illustrates the three ways to calculate demand power using the block method. For illustration purposes, the interval is set to 15 minutes.

PowerLogicTM Series 800 Power Meter Chapter 4—Metering Capabilities

63230-500-225A2 3/2011

Synchronized Demand
The demand calculations can be synchronized by accepting an external pulse input, a command sent over communications, or by synchronizing to the internal real-time clock.

?

Input Synchronized Demand. You can set up the power meter to accept an input such as a demand synch pulse from an external source. The power meter then uses the same time interval as the other meter for each demand calculation. You can use the standard digital input installed on the meter to receive the synch pulse. When setting up this type of demand, you select whether it will be input-synchronized block or inputsynchronized rolling block demand. The rolling block demand requires that you choose a sub-interval. Command Synchronized Demand. Using command synchronized demand, you can synchronize the demand intervals of multiple meters on a communications network. For example, if a PLC input is monitoring a pulse at the end of a demand interval on a utility revenue meter, you could program the PLC to issue a command to multiple meters whenever the utility meter starts a new demand interval. Each time the command is issued, the demand readings of each meter are calculated for the same interval. When setting up this type of demand, you select whether it will be command-synchronized block or command-synchronized rolling block demand. The rolling block demand requires that you choose a sub-interval. See Appendix C—Using the Command Interface on page 83 for more information. Clock Synchronized Demand (Requires PM810LOG). You can synchronize the demand interval to the internal real-time clock in the power meter. This enables you to synchronize the demand to a particular time, typically on the hour. The default time is 12:00 am. If you select another time of day when the demand intervals are to be synchronized, the time must be in minutes from midnight. For example, to synchronize at 8:00 am, select 480 minutes. When setting up this type of demand, you select whether it will be clock-synchronized block or clock-synchronized rolling block demand. The rolling block demand requires that you choose a sub-interval.

?

?

Thermal Demand
The thermal demand method calculates the demand based on a thermal response, which mimics thermal demand meters. The demand calculation updates at the end of each interval. You select the demand interval from 1 to 60 minutes (in 1-minute increments). In Figure 4–5 the interval is set to 15 minutes for illustration purposes.

Time (minutes) next 15-minute interval Calculation updates at the end of each interval

Demand Current
The power meter calculates demand current using the thermal demand method. The default interval is 15 minutes, but you can set the demand current interval between 1 and 60 minutes in 1-minute increments.

PowerLogicTM Series 800 Power Meter Chapter 4—Metering Capabilities

Predicted Demand
The power meter calculates predicted demand for the end of the present interval for kW, kVAR, and kVA demand. This prediction takes into account the energy consumption thus far within the present (partial) interval and the present rate of consumption. The prediction is updated every second. Figure 4–6 illustrates how a change in load can affect predicted demand for the interval.

Change in Load

Peak Demand
In non-volatile memory, the power meter maintains a running maximum for the kWD, kVARD, and kVAD power values, called “peak demand.” The peak for each value is the highest average reading since the meter was last reset. The power meter also stores the date and time when the peak demand occurred. In addition to the peak demand, the power meter also stores the coinciding average 3-phase power factor. The average 3-phase power factor is defined as “demand kW/demand kVA” for the peak demand interval. Table 4–2 on page 30 lists the available peak demand readings from the power meter. You can reset peak demand values from the power meter display. From the Main Menu, select MAINT > RESET > DMD. You can also reset the values over the communications link by using software. NOTE: You should reset peak demand after changes to basic meter setup, such as CT ratio or system type. The power meter also stores the peak demand during the last incremental energy interval. See “Energy Readings” on page 35 for more about incremental energy readings.

Generic Demand
The power meter can perform any of the demand calculation methods, described earlier in this chapter, on up to 10 quantities that you choose using PowerLogic software. For generic demand, do the following:

? ? ?

Select the demand calculation method (thermal, block interval, or synchronized). Select the demand interval (from 5–60 minutes in 1–minute increments) and select the demand sub-interval (if applicable). Select the quantities on which to perform the demand calculation. You must also select the units and scale factor for each quantity.

For each quantity in the demand profile, the power meter stores four values:

? ? ? ?

Partial interval demand value Last completed demand interval value Minimum values (date and time for each is also stored) Peak demand value (date and time for each is also stored)

PowerLogicTM Series 800 Power Meter Chapter 4—Metering Capabilities

63230-500-225A2 3/2011

You can reset the minimum and peak values of the quantities in a generic demand profile by using one of two methods:

? ?

Use PowerLogic software, or Use the command interface. Command 5115 resets the generic demand profile. See Appendix C—Using the Command Interface on page 83 for more about the command interface.

Input Metering Demand
The power meter has five input pulse metering channels, but only one digital input. Digital inputs can be added by installing one or more option modules (PM8M22, PM8M26, or PM8M2222). The input pulse metering channels count pulses received from one or more digital inputs assigned to that channel. Each channel requires a consumption pulse weight, consumption scale factor, demand pulse weight, and demand scale factor. The consumption pulse weight is the number of watt-hours or kilowatt-hours per pulse. The consumption scale factor is a factor of 10 multiplier that determines the format of the value. For example, if each incoming pulse represents 125 Wh, and you want consumption data in watt-hours, the consumption pulse weight is 125 and the consumption scale factor is zero. The resulting calculation is 125 x 100, which equals 125 watt-hours per pulse. If you want the consumption data in kilowatt-hours, the calculation is 125 x 10-3, which equals 0.125 kilowatt-hours per pulse.Time must be taken into account for demand data; so you begin by calculating demand pulse weight using the following formula: watt-hours 3600 seconds pulse - ? ------------------------------------ ? -----------------watts = --------------------------pulse hour second If each incoming pulse represents 125 Wh, using the formula above you get 450,000 watts. If you want demand data in watts, the demand pulse weight is 450 and the demand scale factor is three. The calculation is 450 x 103, which equals 450,000 watts. If you want the demand data in kilowatts, the calculation is 450 x 100, which equals 450 kilowatts. NOTE: The power meter counts each input transition as a pulse. Therefore, an input transition of OFF-to-ON and ON-to-OFF will be counted as two pulses. For each channel, the power meter maintains the following information:

? ? ? ? ?

Total consumption Last completed interval demand—calculated demand for the last completed interval. Partial interval demand—demand calculation up to the present point during the interval. Peak demand—highest demand value since the last reset of the input pulse demand. The date and time of the peak demand is also saved. Minimum demand—lowest demand value since the last reset of the input pulse demand. The date and time of the minimum demand is also saved.

To use the channels feature, first use the display to set up the digital inputs (see “I/O (Input/Output) Setup” on page 18). Then using PowerLogic software, you must set the I/O operating mode to Normal and set up the channels. The demand method and interval that you select applies to all channels.

? Not shown on the power meter display.

The power meter can accumulate the energy values shown in Table 4–3 in one of two modes: signed or unsigned (absolute). In signed mode, the power meter considers the direction of power flow, allowing the magnitude of accumulated energy to increase and decrease. In unsigned mode, the power meter accumulates energy as a positive value, regardless of the direction of power flow. In other words, the energy value increases, even during reverse power flow. The default accumulation mode is unsigned. You can view accumulated energy from the display. The resolution of the energy value will automatically change through the range of 000.000 kWh to 000,000 MWh (000.000 kVAh to 000,000 MVARh), or it can be fixed. See Appendix C—Using the Command Interface on page 83 for the contents of the registers. For conditional accumulated energy readings, you can set the real, reactive, and apparent energy accumulation to OFF or ON when a particular condition occurs. You can do this over the communications link using a command, or from a digital input change. For example, you may want to track accumulated energy values during a particular process that is controlled by a PLC. The power meter stores the date and time of the last reset of conditional energy in non-volatile memory.

Power Analysis Values
The power meter provides a number of power analysis values that can be used to detect power quality problems, diagnose wiring problems, and more. Table 4–6 on page 38 summarizes the power analysis values.

?

THD. Total Harmonic Distortion (THD) is a quick measure of the total distortion present in a waveform and is the ratio of harmonic content to the fundamental. It provides a general indication of the “quality” of a waveform. THD is calculated for both voltage and current. The power meter uses the following equation to calculate THD, where H is the harmonic distortion:

Displacement Power Factor. Power factor (PF) represents the degree to which voltage and current coming into a load are out of phase. Displacement power factor is based on the angle between the fundamental components of current and voltage. Harmonic Values. Harmonics can reduce the capacity of the power system. The power meter determines the individual per-phase harmonic magnitudes and angles for all currents and voltages through the: — 31st harmonic (PM810 with PM810Log, and PM820) or — 63rd harmonic (PM850, PM870) The harmonic magnitudes can be formatted as either a percentage of the fundamental (default), a percentage of the rms value, or the actual rms value. Refer to “Operation with PQ Advanced Enabled” on page 99 for information on how to configure harmonic calculations.

Chapter 5—Input/Output Capabilities
Digital Inputs
The power meter includes one solid-state digital input. A digital input is used to detect digital signals. For example, the digital input can be used to determine circuit breaker status, count pulses, or count motor starts. The digital input can also be associated with an external relay. You can log digital input transitions as events in the power meter’s on-board alarm log. The event is date and time stamped with resolution to the second. The power meter counts OFF-to-ON transitions for each input. You can view the count for each input using the Digital Inputs screen, and you can reset this value using the command interface. Figure 5–1 is an example of the Digital Inputs screen.

The digital input has three operating modes:

? ?

Normal—Use the normal mode for simple on/off digital inputs. In normal mode, digital inputs can be used to count KY pulses for demand and energy calculation. Demand Interval Synch Pulse—you can configure any digital input to accept a demand synch pulse from a utility demand meter (see “Demand Synch Pulse Input” on page 40 of this chapter for more about this topic). For each demand profile, you can designate only one input as a demand synch input. Conditional Energy Control—you can configure one digital input to control conditional energy (see “Reactive energy accumulates in four quadrants” on page 36 in Chapter 4—Metering Capabilities for more about conditional energy).

?

NOTE: By default, the digital input is named DIG IN S02 and is set up for normal mode. For custom setup, use PowerLogic software to define the name and operating mode of the digital input. The name is a 16-character label that identifies the digital input. The operating mode is one of those listed above.

Demand Synch Pulse Input
You can configure the power meter to accept a demand synch pulse from an external source, such as another demand meter. By accepting demand synch pulses through a digital input, the power meter can make its demand interval “window” match the other meter’s demand interval “window.” The power meter does this by “watching” the digital input for a pulse from the other demand meter. When it sees a pulse, it starts a new demand interval and calculates the demand for the preceding interval. The power meter then uses the same time interval as the other meter for each demand calculation. Figure 5–2 illustrates this option. See “Demand Readings” on page 30 in Chapter 4—Metering Capabilities for more about demand calculations. When in demand synch pulse operating mode, the power meter will not start or stop a demand interval without a pulse. The maximum allowable time between pulses is 60 minutes. If 66 minutes (110% of the demand interval) pass before a synch pulse is received, the power meter throws out the demand calculations and begins a new calculation when the next pulse is received. Once in synch with the billing meter, the power meter can be used to verify peak demand charges. Important facts about the power meter’s demand synch feature are listed below:

? ? ?

Any installed digital input can be set to accept a demand synch pulse. Each system can choose whether to use an external synch pulse, but only one demand synch pulse can be brought into the meter for each demand system. One input can be used to synchronize any combination of the demand systems. The demand synch feature can be set up using PowerLogic software.

Relay Output Operating Modes
The relay output defaults to external control, but you can choose whether the relay is set to external or internal control:

? ?

PLSD110140

Power Meter Demand Timing (Slave to Master)

External (remote) control—the relay is controlled either from a PC using PowerLogic software or a programmable logic controller using commands via communications. Power meter alarm (internal) control—the relay is controlled by the power meter in response to a set-point controlled alarm condition, or as a pulse initiator output. Once you’ve set up a relay for power meter control, you can no longer operate the relay remotely. However, you can temporarily override the relay, using PowerLogic software.

NOTE: If any basic setup parameters or I/O setup parameters are modified, all relay outputs will be de-energized. The 11 relay operating modes are as follows:

?

Normal — Externally Controlled: Energize the relay by issuing a command from a remote PC or programmable controller. The relay remains energized until a command to deenergize is issued from the remote PC or programmable controller, or until the

power meter loses control power. When control power is restored, the relay is not automatically re-energized. — Power Meter Alarm: When an alarm condition assigned to the relay occurs, the relay is energized. The relay is not de-energized until all alarm conditions assigned to the relay have dropped out, the power meter loses control power, or the alarms are over-ridden using PowerLogic software. If the alarm condition is still true when the power meter regains control power, the relay will be re-energized.

?

Latched — Remotely Controlled: Energize the relay by issuing a command from a remote PC or programmable controller. The relay remains energized until a command to deenergize is issued from a remote PC or programmable controller, or until the power meter loses control power. When control power is restored, the relay will not be reenergized. — Power Meter Controlled: When an alarm condition assigned to the relay occurs, the relay is energized. The relay remains energized—even after all alarm conditions assigned to the relay have dropped out—until a command to de-energize is issued from a remote PC or programmable controller, until the high priority alarm log is cleared from the display, or until the power meter loses control power. When control power is restored, the relay will not be re-energized if the alarm condition is not TRUE.

?

Timed — Remotely Controlled: Energize the relay by issuing a command from a remote PC or programmable controller. The relay remains energized until the timer expires, or until the power meter loses control power. If a new command to energize the relay is issued before the timer expires, the timer restarts. If the power meter loses control power, the relay will not be re-energized when control power is restored and the timer will reset to zero. — Power Meter Controlled: When an alarm condition assigned to the relay occurs, the relay is energized. The relay remains energized for the duration of the timer. When the timer expires, the relay will de-energize and remain de-energized. If the relay is on and the power meter loses control power, the relay will not be re-energized when control power is restored and the timer will reset to zero.

?

End Of Power Demand Interval This mode assigns the relay to operate as a synch pulse to another device. The output operates in timed mode using the timer setting and turns on at the end of a power demand interval. It turns off when the timer expires.

?

Absolute kWh Pulse This mode assigns the relay to operate as a pulse initiator with a user-defined number of kWh per pulse. In this mode, both forward and reverse real energy are treated as additive (as in a tie circuit breaker).

?

Absolute kVARh Pulse This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVARh per pulse. In this mode, both forward and reverse reactive energy are treated as additive (as in a tie circuit breaker).

?

kVAh Pulse This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVAh per pulse. Since kVA has no sign, the kVAh pulse has only one mode.

?

kWh In Pulse This mode assigns the relay to operate as a pulse initiator with a user-defined number of kWh per pulse. In this mode, only the kWh flowing into the load is considered.

kVARh Out Pulse This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVARh per pulse. In this mode, only the kVARh flowing out of the load is considered.

The last seven modes in the list above are for pulse initiator applications. All Series 800 Power Meters are equipped with one solid-state KY pulse output rated at 100 mA. The solid-state KY output provides the long life—billions of operations—required for pulse initiator applications. The KY output is factory configured with Name = KY, Mode = Normal, and Control = External. To set up custom values, press SETUP > I/O. For detailed instructions, see “I/O (Input/Output) Setup” on page 18. Then using PowerLogic software, you must define the following values for each mechanical relay output:

? ? ? ? ?

Name—A 16-character label used to identify the digital output. Mode—Select one of the operating modes listed above. Pulse Weight—You must set the pulse weight, the multiplier of the unit being measured, if you select any of the pulse modes (last 7 listed above). Timer—You must set the timer if you select the timed mode or end of power demand interval mode (in seconds). Control—You must set the relay to be controlled either remotely or internally (from the power meter) if you select the normal, latched, or timed mode.

For instructions on setting up digital I/Os using software, see your software documentation or help file.

Solid-state KY Pulse Output
This section describes the pulse output capabilities of the power meter. For instructions on wiring the KY pulse output, see “Wiring the Solid-State KY Output” in the installation guide. The power meter’s digital output is generated by a solid-state device that can be used as a KY pulse output. This solid-state relay provides the extremely long life—billions of operations—required for pulse initiator applications. The KY output is a Form-A contact with a maximum rating of 100 mA. Because most pulse initiator applications feed solid-state receivers with low burdens, this 100 mA rating is adequate for most applications. When setting the kWh/pulse value, set the value based on a 2-wire pulse output. For instructions on calculating the correct value, see “Calculating the Kilowatthour-Per-Pulse Value” on page 43 in this chapter. The KY pulse output can be configured to operate in one of 11 operating modes. See “Relay Output Operating Modes” on page 40 for a description of the modes.

In Figure 5–3, the transitions are marked as 1 and 2. Each transition represents the time when the relay contact closes. Each time the relay transitions, the receiver counts a pulse. The power meter can deliver up to 12 pulses per second in a 2-wire application.

Fixed Pulse Output
Fixed pulse output mode generates a fixed duration pulse output that can be associated with kWh consumption. Figure 5–4 shows the difference in pulse duration values when either TRANS mode or PULSE mode is selected. This mode selection is configured on the MAINT > IO > ADVAN menu.

Calculating the Kilowatthour-Per-Pulse Value
The following example illustrates how to calculate kilowatthours per pulse (pulse weight). To calculate this value, first determine the highest kW value you can expect and the required pulse rate. Remember the maximum number of pulses is 8 per second. In this example, the following conditions are set:

? ?

The metered load should not exceed 1600 kW. About two KY pulses per second should normally occur. (If a higher load is reached, the number of pulses per second can increase and still stay within the set limits.)

Step 1: Convert 1600 kW load into kWh/second.
(1600 kW)(1 Hr) = 1600 kWh (1600 kWh) X kWh ------------------------------ = ----------------------1 hour 1 second (1600 kWh) X kWh ------------------------------------ = ----------------------3600 seconds 1 second X = 1600/3600 = 0.444 kWh/second

Step 2: Calculate the kWh required per pulse.
0.444 kWh/second ------------------------------------------------ = 0.222 kWh/pulse 2 pulses/second

Step 3: Adjust for the KY initiator (KY will give one pulse per two transitions of the relay).

Analog Inputs
With a PM8M2222 option module installed, a power meter can accept either voltage or current signals through the analog inputs on the option module. The power meter stores a minimum and a maximum value for each analog input. For technical specifications and instructions on installing and configuring the analog inputs on the PM8M2222, refer to the instruction bulletin (63230-502-200) that ships with the option module. To set up an analog input, you must first set it up from the display. From the SUMMARY screen, select MAINT > SETUP > I/O, then select the appropriate analog input option. Then, in PowerLogic software, define the following values for each analog input:

? ? ? ? ?

Name—a 16-character label used to identify the analog input. Units—the units of the monitored analog value (for example, “psi”). Scale factor—multiplies the units by this value (such as tenths or hundredths). Report Range Lower Limit—the value the Power Meter reports when the input reaches a minimum value. When the input current is below the lowest valid reading, the Power Meter reports the lower limit. Report Range Upper Limit—the value the power meter reports when the input reaches the maximum value. When the input current is above highest valid reading, the Power Meter reports the upper limit.

PowerLogicTM Series 800 Power Meter Chapter 6—Alarms

Chapter 6—Alarms
This section describes the alarm features on all Series 800 Power Meters. For information about advanced alarm features, go to “Advanced Alarms” on page 53.

Basic Alarms
The power meter can detect over 50 alarm conditions, including over or under conditions, digital input changes, phase unbalance conditions, and more. It also maintains a counter for each alarm to keep track of the total number of occurrences. A complete list of default basic alarm configurations are described in Table 6–5 on page 51 . In addition, you can set up your own custom alarms after installing an input/output module (PM8M22, PM8M26, or PM8M2222). When one or more alarm conditions are true, the power meter will execute a task automatically. When an alarm is active, the ! alarm icon appears in the upper-right corner of the power meter display. If a PM810LOG is installed on a PM810, PowerLogic software can be used to set up each alarm condition to force data log entries in a single data log file. For the PM820, PM850, and PM870 PowerLogic software can be used to set up each alarm condition to force data log entries in up to three user-defined data log files. See Chapter 7—Logging on page 57 for more about data logging. NOTE: PM820 only supports one data log.

Basic Alarm Groups
When using a default alarm, you first choose the alarm group that is appropriate for the application. Each alarm condition is assigned to one of these alarm groups: Whether you are using a default alarm or creating a custom alarm, you first choose the alarm group that is appropriate for the application. Each alarm condition is assigned to one of these alarm groups:

? ? ?

Standard—Standard alarms have a detection rate of 1 second and are useful for detecting conditions such as over current and under voltage. Up to 40 alarms can be set up in this alarm group. Digital—Digital alarms are triggered by an exception such as the transition of a digital input or the end of an incremental energy interval. Up to 12 alarms can be set up in this group. Custom—The power meter has many pre-defined alarms, but you can also set up your own custom alarms using PowerLogic software. For example, you may need to alarm on the ON-to-OFF transition of a digital input. To create this type of custom alarm: 1. Select the appropriate alarm group (digital in this case). 2. Select the type of alarm (described in Table 6–6 on page 52 ). 3. Give the alarm a name. 4. Save the custom alarm. After creating a custom alarm, you can configure it by applying priorities, setting pickups and dropouts (if applicable), and so forth.

Both the power meter display and PowerLogic software can be used to set up standard, digital, and custom alarm types.

Setpoint-driven Alarms
Many of the alarm conditions require that you define setpoints. This includes all alarms for over, under, and phase unbalance alarm conditions. Other alarm conditions such as digital input transitions and phase reversals do not require setpoints. For those alarm conditions that require setpoints, you must define the following information:

? ? ? ?

Pickup Setpoint Pickup Delay Dropout Setpoint Dropout Delay NOTE: Alarms with both Pickup and Dropout setpoints set to zero are invalid. The following two figures will help you understand how the power meter handles setpointdriven alarms. Figure 6–1 shows what the actual alarm Log entries for Figure 6–2 might look like, as displayed by PowerLogic software. NOTE: The software does not actually display the codes in parentheses—EV1, EV2, Max1, Max2. These are only references to the codes in Figure 6–2.

Dropout Delay EV2 Alarm Period

EV1—The power meter records the date and time that the pickup setpoint and time delay were satisfied, and the maximum value reached (Max1) during the pickup delay period (?T). Also, the power meter performs any tasks assigned to the event such as waveform captures or forced data log entries. EV2—The power meter records the date and time that the dropout setpoint and time delay were satisfied, and the maximum value reached (Max2) during the alarm period. The power meter also stores a correlation sequence number (CSN) for each event (such as Under Voltage Phase A Pickup, Under Voltage Phase A Dropout). The CSN lets you relate pickups and dropouts in the alarm log. You can sort pickups and dropouts by CSN to correlate the pickups and dropouts of a particular alarm. The pickup and dropout entries of an alarm will have the same CSN. You can also calculate the duration of an event by looking at pickups and dropouts with the same CSN.

Priorities
Each alarm also has a priority level. Use the priorities to distinguish between events that require immediate action and those that do not require action.

? ? ? ?

High priority—if a high priority alarm occurs, the display informs you in two ways: the LED backlight on the display flashes until you acknowledge the alarm and the alarm icon blinks while the alarm is active. Medium priority—if a medium priority alarm occurs, the alarm icon blinks only while the alarm is active. Once the alarm becomes inactive, the alarm icon stops blinking and remains on the display. Low priority—if a low priority alarm occurs, the alarm icon blinks only while the alarm is active. Once the alarm becomes inactive, the alarm icon disappears from the display. No priority—if an alarm is set up with no priority, no visible representation will appear on the display. Alarms with no priority are not entered in the Alarm Log. See Chapter 7—Logging for alarm logging information.

If multiple alarms with different priorities are active at the same time, the display shows the alarm message for the last alarm that occurred. For instructions on setting up alarms from the power meter display, see “ALARM (Alarms) Setup” on page 17.

? ? ?

Values that are too large to fit into the display may require scale factors. For more information on scale factors, refer to “Changing Scale Factors” on page 91. Relays can be configured as normal, latched, or timed. See “Relay Output Operating Modes” on page 40 for more information. When the alarm occurs, the power meter operates any specified relays. There are two ways to release relays that are in latched mode: — Issue a command to de-energize a relay. See Appendix C—Using the Command Interface on page 83 for instructions on using the command interface, or — Acknowledge the alarm in the high priority log to release the relays from latched mode. From the main menu of the display, press ALARM to view and acknowledge unacknowledged alarms.

The list that follows shows the types of alarms available for some common alarm functions: NOTE: Voltage based alarm setpoints depend on your system configuration. Alarm setpoints for 3-wire systems are VL-L values while 4-wire systems are VL-N values.

Under-voltage: Pickup and dropout setpoints are entered in volts. The per-phase undervoltage alarm occurs when the per-phase voltage is equal to or below the pickup setpoint long enough to satisfy the specified pickup delay (in seconds). The under-voltage alarm clears when the phase voltage remains above the dropout setpoint for the specified dropout delay period. Over-voltage: Pickup and dropout setpoints are entered in volts. The per-phase overvoltage alarm occurs when the per-phase voltage is equal to or above the pickup setpoint long enough to satisfy the specified pickup delay (in seconds). The over-voltage alarm clears when the phase voltage remains below the dropout setpoint for the specified dropout delay period. Unbalance Current: Pickup and dropout setpoints are entered in tenths of percent, based on the percentage difference between each phase current with respect to the average of all phase currents. For example, enter an unbalance of 7% as 70. The unbalance current alarm occurs when the phase current deviates from the average of the phase currents, by the percentage pickup setpoint, for the specified pickup delay. The alarm clears when the percentage difference between the phase current and the average of all phases remains below the dropout setpoint for the specified dropout delay period. Unbalance Voltage: Pickup and dropout setpoints are entered in tenths of percent, based on the percentage difference between each phase voltage with respect to the average of all phase voltages. For example, enter an unbalance of 7% as 70. The unbalance voltage alarm occurs when the phase voltage deviates from the average of the phase voltages, by the percentage pickup setpoint, for the specified pickup delay. The alarm clears when the percentage difference between the phase voltage and the average of all phases remains below the dropout setpoint for the specified dropout delay (in seconds). Phase Loss—Current: Pickup and dropout setpoints are entered in amperes. The phase loss current alarm occurs when any current value (but not all current values) is equal to or below the pickup setpoint for the specified pickup delay (in seconds). The alarm clears when one of the following is true:

? ?

All of the phases remain above the dropout setpoint for the specified dropout delay, or All of the phases drop below the phase loss pickup setpoint.

If all of the phase currents are equal to or below the pickup setpoint, during the pickup delay, the phase loss alarm will not activate. This is considered an under current condition. It should be handled by configuring the under current alarm functions. Phase Loss—Voltage: Pickup and dropout setpoints are entered in volts. The phase loss voltage alarm occurs when any voltage value (but not all voltage values) is equal to or below the pickup setpoint for the specified pickup delay (in seconds). The alarm clears when one of the following is true:

? ?

All of the phases remain above the dropout setpoint for the specified dropout delay (in seconds), OR All of the phases drop below the phase loss pickup setpoint.

If all of the phase voltages are equal to or below the pickup setpoint, during the pickup delay, the phase loss alarm will not activate. This is considered an under voltage condition. It should be handled by configuring the under voltage alarm functions. Reverse Power: Pickup and dropout setpoints are entered in kilowatts or kVARs. The reverse power alarm occurs when the power flows in a negative direction and remains at or below the negative pickup value for the specified pickup delay (in seconds). The alarm clears when the power reading remains above the dropout setpoint for the specified dropout delay (in seconds). Phase Reversal: Pickup and dropout setpoints do not apply to phase reversal. The phase reversal alarm occurs when the phase voltage rotation differs from the default phase rotation. The power meter assumes that an ABC phase rotation is normal. If a CBA phase rotation is normal, the user must change the power meter’s phase rotation from ABC (default) to CBA. To change the phase rotation from the display, from the main menu select Setup > Meter > Advanced. For more information about changing the phase rotation setting of the power meter, refer to “ADVAN (Advanced) Power Meter Setup Features” on page 19.

PowerLogicTM Series 800 Power Meter Chapter 6—Alarms

Scale Factors
A scale factor is the multiplier expressed as a power of 10. For example, a multiplier of 10 is represented as a scale factor of 1, since 101=10; a multiplier of 100 is represented as a scale factor of 2, since 102=100. This allows you to make larger values fit into the register. Normally, you do not need to change scale factors. If you are creating custom alarms, you need to understand how scale factors work so that you do not overflow the register with a number larger than what the register can hold. When PowerLogic software is used to set up alarms, it automatically handles the scaling of pickup and dropout setpoints. When creating a custom alarm using the power meter’s display, do the following:

? ?

Determine how the corresponding metering value is scaled, and Take the scale factor into account when entering alarm pickup and dropout settings.

Pickup and dropout settings must be integer values in the range of -32,767 to +32,767. For example, to set up an under voltage alarm for a 138 kV nominal system, decide upon a setpoint value and then convert it into an integer between -32,767 and +32,767. If the under voltage setpoint were 125,000 V, this would typically be converted to 12500 x 10 and entered as a setpoint of 12500. Six scale groups are defined (A through F). The scale factor is preset for all factoryconfigured alarms. Table 6–2 lists the available scale factors for each of the scale groups. If you need either an extended range or more resolution, select any of the available scale factors to suit your need. Refer to “Changing Scale Factors” on page 91 of Appendix C—Using the Command Interface.

Scaling Alarm Setpoints
This section is for users who do not have PowerLogic software and need to set up alarms from the power meter display. It explains how to scale alarm setpoints. When the power meter is equipped with a display, most metered quantities are limited to five characters (plus a positive or negative sign). The display will also show the engineering units applied to that quantity. To determine the proper scaling of an alarm setpoint, view the register number for the associated scale group. The scale factor is the number in the Dec column for that register. For example, the register number for Scale D to Phase Volts is 3212. If the number in the Dec column is 1, the scale factor is 10 (101=10). Remember that scale factor 1 in Table 6–3 on page 50 for Scale Group D is measured in kV. Therefore, to define an alarm setpoint of 125 kV, enter 12.5 because 12.5 multiplied by 10 is 125. Below is a table listing the scale groups and their register numbers.

Standard Speed If the test register value exceeds the setpoint long enough to satisfy the pickup delay period, the alarm condition will be true. When the value in the test register falls below the dropout setpoint long enough to satisfy the dropout delay period, the alarm will drop out. Pickup and dropout setpoints are positive, delays are in seconds. If the absolute value in the test register exceeds the setpoint long enough to satisfy the pickup delay period, the alarm condition will be true. When absolute the value in the test register falls below the dropout setpoint long enough to satisfy the dropout delay period, the alarm will drop out. Pickup and dropout setpoints are positive, delays are in seconds. If the absolute value in the test register exceeds the setpoint long enough to satisfy the pickup delay period, the alarm condition will be true. When absolute the value in the test register falls below the dropout setpoint long enough to satisfy the dropout delay period, the alarm will drop out. This alarm will only hold true for reverse power conditions. Positive power values will not cause the alarm to occur. Pickup and dropout setpoints are positive, delays are in seconds. If the test register value is below the setpoint long enough to satisfy the pickup delay period, the alarm condition will be true. When the value in the test register rises above the dropout setpoint long enough to satisfy the dropout delay period, the alarm will drop out. Pickup and dropout setpoints are positive, delays are in seconds. If the absolute value in the test register is below the setpoint long enough to satisfy the pickup delay period, the alarm condition will be true. When the absolute value in the test register rises above the dropout setpoint long enough to satisfy the dropout delay period, the alarm will drop out. Pickup and dropout setpoints are positive, delays are in seconds. The phase reversal alarm will occur whenever the phase voltage waveform rotation differs from the default phase rotation. The ABC phase rotation is assumed to be normal. If a CBA phase rotation is normal, the user should reprogram the power meter’s phase rotation ABC to CBA phase rotation. The pickup and dropout setpoints for phase reversal do not apply. The phase loss voltage alarm will occur when any one or two phase voltages (but not all) fall to the pickup value and remain at or below the pickup value long enough to satisfy the specified pickup delay. When all of the phases remain at or above the dropout value for the dropout delay period, or when all of the phases drop below the specified phase loss pickup value, the alarm will drop out. Pickup and dropout setpoints are positive, delays are in seconds. The phase loss current alarm will occur when any one or two phase currents (but not all) fall to the pickup value and remain at or below the pickup value long enough to satisfy the specified pickup delay. When all of the phases remain at or above the dropout value for the dropout delay period, or when all of the phases drop below the specified phase loss pickup value, the alarm will drop out. Pickup and dropout setpoints are positive, delays are in seconds. The leading power factor alarm will occur when the test register value becomes more leading than the pickup setpoint (such as closer to 0.010) and remains more leading long enough to satisfy the pickup delay period. When the value becomes equal to or less leading than the dropout setpoint, that is 1.000, and remains less leading for the dropout delay period, the alarm will drop out. Both the pickup setpoint and the dropout setpoint must be positive values representing leading power factor. Enter setpoints as integer values representing power factor in thousandths. For example, to define a dropout setpoint of 0.5, enter 500. Delays are in seconds. The lagging power factor alarm will occur when the test register value becomes more lagging than the pickup setpoint (such as closer to –0.010) and remains more lagging long enough to satisfy the pickup delay period. When the value becomes equal to or less lagging than the dropout setpoint and remains less lagging for the dropout delay period, the alarm will drop out. Both the pickup setpoint and the dropout setpoint must be positive values representing lagging power factor. Enter setpoints as integer values representing power factor in thousandths. For example, to define a dropout setpoint of –0.5, enter 500. Delays are in seconds. The digital input transition alarms will occur whenever the digital input changes from off to on. The alarm will dropout when the digital input changes back to on from off. The pickup and dropout setpoints and delays do not apply. The digital input transition alarms will occur whenever the digital input changes from on to off.The alarm will dropout when the digital input changes back to off from on. The pickup and dropout setpoints and delays do not apply. This is a internal signal from the power meter and can be used, for example, to alarm at the end of an interval or when the power meter is reset. Neither the pickup and dropout delays nor the setpoints apply.

Advanced Alarm Groups
In addition to the basic alarm groups (see “Basic Alarm Groups” on page 45), the following advanced alarm groups are available.

? ?

Boolean—Boolean alarms use Boolean logic to combine up to four enabled alarms. You can choose from the Boolean logic operands: AND, NAND, OR, NOR, or XOR to combine your alarms. Up to 10 alarms can be set up in this group. Disturbance (PM870)—Disturbance alarms have a detection rate of half a cycle and are useful for detecting voltage sags and swells. The Power Meter comes configured with 12 default voltage sag and swell alarms; current sag and swell alarms are available by configuring custom alarms. Up to 12 disturbance alarms can be set up in this group. For more information about disturbance monitoring, see Chapter 9—Disturbance Monitoring (PM870) on page 65. Custom—The power meter has many pre-defined alarms, but you can also set up your own custom alarms using PowerLogic software. For example, you may need to alarm on a sag condition for current A. To create this type of custom alarm: 1. Select the appropriate alarm group (Disturbance in this case). 2. Delete any of the default alarms you are not using from the disturbance alarms group (for example, Sag Vbc). The Add button should be available now. 3. Click Add, then select Disturbance, Sag, and Current A. 4. Give the alarm a name. 5. Save the custom alarm. After creating a custom alarm, you can configure it by applying priorities, setting pickups and dropouts (if applicable), and so forth.

?

PowerLogic software can be used to configure any of the advanced alarm types, but the power meter display cannot be used. Also, use PowerLogic software to delete an alarm and create a new alarm for evaluating other metered quantities.

Alarm Levels
Using PowerLogic software with a PM850 or PM870, multiple alarms can be set up for one particular quantity (parameter) to create alarm “levels”. You can take different actions depending on the severity of the alarm. For example, you could set up two alarms for kW Demand. A default alarm already exists for kW Demand, but you could create another custom alarm for kW Demand, selecting different pickup points for it. The custom kW Demand alarm, once created, will appear in the standard alarm list. For illustration purposes, let’s set the default kW Demand alarm to 120 kW and the new custom alarm to 150 kW. One alarm named kW Demand ; the other kW Demand 150kW as shown in Figure 6–3. If you choose to set up two alarms for the same quantity, use slightly different names to distinguish which alarm is active. The display can hold up to 15 characters for each name. You can create up to 10 alarm levels for each quantity.

Alarm Log
By default, the power meter can log the occurrence of any alarm condition. Each time an alarm occurs it is entered into the alarm log. The alarm log in the power meter stores the pickup and dropout points of alarms along with the date and time associated with these alarms. You select whether the alarm log saves data as first-in-first-out (FIFO) or fill and hold. With PowerLogic software, you can view and save the alarm log to disk, and reset the alarm log to clear the data out of the power meter’s memory.

Alarm Log Storage
The power meter stores alarm log data in non-volatile memory. The size of the alarm log is fixed at 100 records.

Maintenance Log
The power meter stores a maintenance log in non-volatile memory. The file has a fixed record length of four registers and a total of 40 records. The first register is a cumulative counter over the life of the power meter. The last three registers contain the date/time of when the log was updated. Table 7–4 describes the values stored in the maintenance log. These values are cumulative over the life of the power meter and cannot be reset. NOTE: Use PowerLogic software to view the maintenance log.

Alarm-driven Data Log Entries
The PM810 with a PM810LOG can detect over 50 alarm conditions, including over/under conditions, digital input changes, phase unbalance conditions, and more. (See Chapter 6—Alarms on page 45 for more information.) Use PowerLogic software to assign each alarm condition one or more tasks, including forcing data log entries into Data Log 1. The PM820, PM850, and PM870 can detect over 50 alarm conditions, including over/under conditions, digital input changes, phase unbalance conditions, and more. (See Chapter 6—Alarms on page 45 for more information.) Use PowerLogic software to assign each alarm condition one or more tasks, including forcing data log entries into one or more data log files. For example, assume you have defined three data log files. Using PowerLogic software, you could select an alarm condition such as “Overcurrent Phase A” and set up the power meter to force data log entries into any of the three log files each time the alarm condition occurs.

Organizing Data Log Files (PM850, PM870)
You can organize data log files in many ways. One possible way is to organize log files according to the logging interval. You might also define a log file for entries forced by alarm conditions. For example, you could set up three data log files as follows: Data Log 1: Log voltage every minute. Make the file large enough to hold 60 entries so that you could look back over the last hour’s voltage readings. Log energy once every day. Make the file large enough to hold 31 entries so that you could look back over the last month and see daily energy use. Report by exception. The report by exception file contains data log entries that are forced by the occurrence of an alarm condition. See the topic above, “Alarm-driven Data Log Entries”, for more information.

Data Log 2:

Data Log 3:

NOTE: The same data log file can support both scheduled and alarm-driven entries.

Billing Log
The PM810 with a PM810LOG, PM820, PM850 and PM870 Power Meters store a configurable billing log that updates every 10 to 1,440 minutes (the default interval 60 minutes). Data is stored by month, day, and the specified interval in minutes. The log contains 24 months of monthly data and 32 days of daily data, but because the maximum amount of memory for the billing log is 64 KB, the number of recorded intervals varies based on the number of registers recorded in the billing log. For example, using all of the registers listed in Table 7–6, the billing log holds 12 days of data at 60-minute intervals. This value is calculated by doing the following: 1. Calculate the total number of registers used (see Table 7–6 on page 63 for the number of registers). In this example, all 26 registers are used. 2. Calculate the number of bytes used for the 24 monthly records. 24 records (26 registers x 2 bytes/register) = 1,248 3. Calculate the number of bytes used for the 32 daily records. 32 (26 x 2) = 1,664 4. Calculate the number of bytes used each day (based on 15 minute intervals). 96 (26 x 2) = 4,992 5. Calculate the number of days of 60-minute interval data recorded by subtracting the values from steps 2 and 3 from the total log file size of 65,536 bytes and then dividing by the value in step 4. (65,536 – 1,248 – 1,664) ??4,992 = 12 days

Waveform Capture
A waveform capture can be initiated manually or by an alarm trigger to analyze steadystate or disturbance events. This waveform provides information about individual harmonics, which PowerLogic software calculates through the 63rd harmonic. It also calculates total harmonic distortion (THD) and other power quality parameters. NOTE: Disturbance waveform captures are available in the PM870 only. In the PM850, the waveform capture records five individual three-cycle captures at 128 samples per cycle simultaneously on all six metered channels. In the PM870, there is a range of one to five waveform captures, but the number of cycles captured varies based on the number of samples per cycle and the number of channels selected in your software. Use Figure 8–1 to determine the number of cycles captured.

PowerLogicTM Series 800 Power Meter Chapter 8—Waveform Capture

63230-500-225A2 3/2011

Initiating a Waveform
Using PowerLogic software from a remote PC, initiate a waveform capture manually by selecting the power meter and issuing the acquire command. The software will automatically retrieve the waveform capture from the power meter. You can display the waveform for all three phases, or zoom in on a single waveform, which includes a data block with extensive harmonic data. See your software’s online help or documentation for instructions.

Waveform Storage
The power meter can store multiple captured waveforms in its non-volatile memory. The number of waveforms stored is based on the number selected. There are a maximum of five stored waveforms. All stored waveform data is retained on power loss.

Waveform Storage Modes
There are two ways to store waveform captures: “FIFO” and “Fill and Hold.” FIFO mode allows the file to fill up the waveform capture file. After the file is full, the oldest waveform capture is removed, and the most recent waveform capture is added to the file. The Fill and Hold mode fills the file until the configured number of waveform captures is reached. New waveform captures cannot be added until the file is cleared.

How the Power Meter Captures an Event
When the power meter senses the trigger—that is, when the digital input transitions from OFF to ON, or an alarm condition is met—the power meter transfers the cycle data from its data buffer into the memory allocated for event captures.

Channel Selection in PowerLogic Software
Using PowerLogic software, you can select up to six channels to include in the waveform capture. See your software’s online help or documentation for instructions.

PowerLogicTM Series 800 Power Meter Chapter 9—Disturbance Monitoring (PM870)

Chapter 9—Disturbance Monitoring (PM870)
This chapter provides background information about disturbance monitoring and describes how to use the PM870 to continuously monitor for disturbances on the current and voltage inputs.

About Disturbance Monitoring
Momentary voltage disturbances are an increasing concern for industrial plants, hospitals, data centers, and other commercial facilities because modern equipment used in those facilities tends to be more sensitive to voltage sags, swells, and momentary interruptions. The power meter can detect these events by continuously monitoring and recording current and voltage information on all metered channels. Using this information, you can diagnose equipment problems resulting from voltage sags or swells and identify areas of vulnerability, enabling you to take corrective action. The interruption of an industrial process because of an abnormal voltage condition can result in substantial costs, which manifest themselves in many ways:

? ? ? ?

labor costs for cleanup and restart lost productivity damaged product or reduced product quality delivery delays and user dissatisfaction

The entire process can depend on the sensitivity of a single piece of equipment. Relays, contactors, adjustable speed drives, programmable controllers, PCs, and data communication networks are all susceptible to power quality problems. After the electrical system is interrupted or shut down, determining the cause may be difficult. Several types of voltage disturbances are possible, each potentially having a different origin and requiring a separate solution. A momentary interruption occurs when a protective device interrupts the circuit that feeds a facility. Swells and over-voltages can damage equipment or cause motors to overheat. Perhaps the biggest power quality problem is the momentary voltage sag caused by faults on remote circuits. A voltage sag is a brief (1/2 cycle to 1 minute) decrease in rms voltage magnitude. A sag is typically caused by a remote fault somewhere on the power system, often initiated by a lightning strike. In Figure 9–1, the utility circuit breaker cleared the fault near plant D. The fault not only caused an interruption to plant D, but also resulted in voltage sags to plants A, B, and C. NOTE: The PM870 is able to detect sag and swell events less than 1/2 cycle duration. However, it may be impractical to have setpoints more sensitive than 10% for voltage and current fluctuations.

Utility Transformer

2 Plant B

3 Plant C

X 4 Plant D
Fault A fault near plant D, cleared by the utility circuit breaker, can still affect plants A, B, and C, resulting in a voltage sag.

System voltage sags are much more numerous than interruptions, since a wider part of the distribution system is affected. And, if reclosers are operating, they may cause repeated sags. The PM870 can record recloser sequences, too. The waveform in Figure 9–2 shows the magnitude of a voltage sag, which persists until the remote fault is cleared.
Figure 9–2: Waveform showing voltage sag caused by a remote fault and lasting five cycles

With the information obtained from the PM870 during a disturbance, you can solve disturbance-related problems, including the following:

?

Obtain accurate measurement from your power system — Identify the number of sags, swells, or interruptions for evaluation — Accurately distinguish between sags and interruptions, with accurate recording of the time and date of the occurrence — Provide accurate data in equipment specification (ride-through, etc.)

?

Determine equipment sensitivity — Compare equipment sensitivity of different brands (contactor dropout, drive sensitivity, etc.) — Diagnose mysterious events such as equipment malfunctions, contactor dropout, computer glitches, etc. — Compare actual sensitivity of equipment to published standards

Capabilities of the PM870 During an Event
The PM870 calculates rms magnitudes, based on 128 data points per cycle, every 1/2 cycle. This ensures that even sub-cycle duration rms variations are not missed. The power meter is configured with 12 default voltage disturbance alarms for all voltage channels. Current sag and swell alarms are available by configuring custom alarms. A maximum of 12 disturbance alarms are available. When the PM870 detects a sag or swell, it can perform the following actions:

?

Perform a waveform capture with a resolution from 185 cycles at 16 samples per cycle on one channel down to 3 cycles at 128 samples per cycle on all six channels of the metered current and voltage inputs (see Figure 8–1 on page 63). Use PowerLogic software to set up the event capture and retrieve the waveform. Record the event in the alarm log. When an event occurs, the PM870 updates the alarm log with an event date and time stamp with 1 millisecond resolution for a sag or swell pickup, and an rms magnitude corresponding to the most extreme value of the sag or swell during the event pickup delay. Also, the PM870 can record the sag or swell dropout in the alarm log at the end of the disturbance. Information stored includes: a dropout time stamp with 1 millisecond resolution and a second rms magnitude corresponding to the most extreme value of the sag or swell. Use PowerLogic software to view the alarm log. NOTE: The Power Meter display has a 1 second resolution. Force a data log entry in up to 3 independent data logs. Use PowerLogic software to set up and view the data logs. Operate any output relays when the event is detected. Indicate the alarm on the display by flashing the maintenance icon to show that a sag or swell event has occurred.

PowerLogicTM Series 800 Power Meter Chapter 10—Maintenance and Troubleshooting

Chapter 10—Maintenance and Troubleshooting
Introduction
This chapter describes information related to maintenance of your power meter. The power meter does not contain any user-serviceable parts. If the power meter requires service, contact your local sales representative. Do not open the power meter. Opening the power meter voids the warranty.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH ? Do not attempt to service the power meter. CT and PT inputs may contain hazardous currents and voltages. ? Only authorized service personnel from the manufacturer should service the power meter. Failure to follow these instructions will result in death or serious injury.

CAUTION
HAZARD OF EQUIPMENT DAMAGE ? Do not perform a Dielectric (Hi-Pot) or Megger test on the power meter. High voltage testing of the power meter may damage the unit. ? Before performing Hi-Pot or Megger testing on any equipment in which the power meter is installed, disconnect all input and output wires to the power meter. Failure to follow these instructions can result in injury or equipment damage.

Power Meter Memory
The power meter uses its non-volatile memory (RAM) to retain all data and metering configuration values. Under the operating temperature range specified for the power meter, this non-volatile memory has an expected life of up to 100 years. The power meter stores its data logs on a memory chip, which has a life expectancy of up to 20 years under the operating temperature range specified for the power meter. The life of the internal batterybacked clock is over 10 years at 25°C. NOTE: Life expectancy is a function of operating conditions; this does not constitute any expressed or implied warranty.

Date and Time Settings
The clock in the PM810 is volatile. Therefore, the PM810 returns to the default clock date/time of 12:00 AM 01-01-1980 each time the meter resets. Reset occurs when the meter loses control power or you change meter configuration parameters including selecting the time format (24-hr or AM/PM) or date format. To avoid resetting clock time more than once, always set the clock date and time last. The PM810LOG (optional module) provides a non-volatile clock in addition to on-board logging and individual harmonics readings for the PM810.

PowerLogicTM Series 800 Power Meter Chapter 10—Maintenance and Troubleshooting

Troubleshooting
The information in Table 10–1 on page 72 describes potential problems and their possible causes. It also describes checks you can perform or possible solutions for each. If you still cannot resolve the problem after referring to this table, contact the your local Schneider Electric sales representative for assistance.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH ? Apply appropriate personal protective equipment (PPE) and follow safe electrical practices. For example, in the United States, see NFPA 70E. ? This equipment must be installed and serviced only by qualified personnel. ? Turn off all power supplying this equipment before working on or inside. ? Always use a properly rated voltage sensing device to confirm that all power is off. ? Carefully inspect the work area for tools and objects that may have been left inside the equipment. ? Use caution while removing or installing panels so that they do not extend into the energized bus; avoid handling the panels which could cause personal injury. Failure to follow these instructions will result in death or serious injury.

Heartbeat LED
The heartbeat LED helps to troubleshoot the power meter. The LED works as follows:

? ? ?

Normal operation — the LED flashes at a steady rate during normal operation. Communications — the LED flash rate changes as the communications port transmits and receives data. If the LED flash rate does not change when data is sent from the host computer, the power meter is not receiving requests from the host computer. Hardware — if the heartbeat LED remains lit and does not flash ON and OFF, there is a hardware problem. Do a hard reset of the power meter (turn OFF power to the power meter, then restore power to the power meter). If the heartbeat LED remains lit, contact your local sales representative. Control power and display — if the heartbeat LED flashes, but the display is blank, the display is not functioning properly. If the display is blank and the LED is not lit, verify that control power is connected to the power meter.

PowerLogicTM Series 800 Power Meter Appendix A—Instrument Transformer Wiring: Troubleshooting Tables

Appendix A—Instrument Transformer Wiring: Troubleshooting Tables
Abnormal readings in an installed meter can sometimes signify improper wiring. This appendix is provided as an aid in troubleshooting potential wiring problems.

Using This Appendix
The following pages contain “Case” tables arranged in sections. These tables show a variety of symptoms and probable causes. Section I: Check these tables first. These are common problems for 3-wire and 4-wire systems that can occur regardless of system type. Section II: Check these tables if troubleshooting more complex 3-wire systems. Section III: Check these tables if troubleshooting more complex 4-wire systems. The symptoms listed are “ideal,” and some judgment should be exercised when troubleshooting. For example, if the kW reading is 25, but you know that it should be about 300 kW, go to a table where “kW = 0” is listed as one of the symptoms. Because it is nearly impossible to address all combinations of multiple wiring mistakes or other problems that can occur (e.g., blown PT fuses, missing PT neutral ground connection), this guide generally addresses only one wiring problem at a time. Before trying to troubleshoot wiring problems, it is imperative that all instantaneous readings be available for reference. Specifically, those readings should include the following:

? ? ? ? ? ? ?

line-to-line voltages line-to-neutral voltages phase currents power factor kW kVAR kVA

What is Normal?

Most power systems have a lagging (inductive) power factor. The only time a leading power factor is expected is if power factor correction capacitors are switched in or over-excited synchronous motors with enough capacitive kVARS are on-line to overcorrect the power factor to leading. Some uninterruptable power supplies (UPS) also produce a leading power factor. "Normal" lagging power system readings are as follows:

? ? ? ? ? ?

Positive kW = ? 3 ? V AB ? I 3 ? Avg ? PF 3 ? Avg ? ? 1000 Negative kVAR = ? ? kVA ? – ? kW ? ? ? 1000 kVA (always positive) = ? 3 ? V AB ? I 3 ? Avg ? ? 1000 PF 3 ? Avg = lagging in the range 0.70 to 1.00 (for 4-wire systems, all phase PFs are about the same) Phase currents approximately equal Phase voltages approximately equal
2 2

A quick check for proper readings consists of kW comparisons (calculated using the previous equation and compared to the meter reading) and a reasonable lagging 3-phase average power factor reading. If these checks are okay, there is little reason to continue to check for wiring problems.

Section I—Case A
Symptoms: 3-Wire and 4-Wire Possible Causes
? ? ?

CT secondaries shorted. Less than 2% load on power meter based on CT ratio.

Zero amps Zero kW, kVAR, kVA

?

Example: with 100/5 CT's, at least 2A must flow through CT window for power meter to “wake up.”

Section I—Case B
Symptoms: 3-Wire and 4-Wire
? ? ?

Possible Causes
?

Negative kW of expected magnitude Positive kVAR Normal lagging power factor

All three CT polarities backwards; could be CTs are physically mounted with primary polarity mark toward the load instead of toward source or secondary leads swapped. All three PT polarities backwards; again, could be on primary or secondary.

?

NOTE: Experience shows CTs are usually the problem.

Section I—Case C
Symptoms: 3-Wire and 4-Wire Possible Causes
? ?

Frequency is an abnormal value; may or may not be a multiple of 50/60 Hz.

PTs primary and/or secondary neutral common not grounded (values as high as 275 Hz and as low as 10 Hz have been seen). System grounding problem at the power distribution transformer (such as utility transformer), though this is not likely.

Currents and voltages approximately balanced kW = near 0 kVAR = near 0 PF can be any value, probably fluctuating

CT secondary leads are swapped (A-phase lead on C-phase terminal and vice versa). PT secondary leads are swapped (A-phase lead on C-phase terminal and vice versa).

?

Section II—Case B
Symptoms: 3-Wire

Possible Causes

Phase B current is 3 higher than A and C (except in System Type 31). kVA = about half of the expected magnitude kW and kVAR can be positive or negative, less ? than about half of the expected magnitude. PF can be any value, probably a low leading value. One CT polarity is backwards.

? ?

Possible Causes
?

kW = 0 or low, with magnitude less than kVAR kVAR = positive or negative with magnitude of close to what is expected for kW kVA = expected magnitude PF = near 0 up to about 0.7 lead

Either the two voltage leads are swapped OR the two current leads are swapped AND one instrument transformer has backwards polarity. (look for V CA = 3 high or phase B current = 3 high) The power meter is metering a purely capacitive load (this is unusual); in this case kW and kVAR will be positive and PF will be near 0 lead.

Section II—Case E
Symptoms: 3-Wire
? ? ?

Possible Causes
? ?

One phase current reads 0 kVA = about 1/2 of the expected value kW, kVAR, and power factor can be positive or negative of any value

The CT on the phase that reads 0 is short-circuited. Less than 2% current (based on CT ratio) flowing through the CT on the phase that reads 0.

Troubleshooting Diagnosis

? ? ? ? ? ? ? ? ?

Power factors cannot be correct . None of the “Section II” symptoms exist, so proceed to the 4-wire troubleshooting (“Section IV”). Cannot calculate kW because 3-phase power factor cannot be right, so calculate kVA instead. Calculated kVA = ? 3 ? V ab ? I 3 ? Avg ? ? 1000 = ? 1.732 ? 495 ? 908 ? ? 1000 = 778 kVA Power meter reading is essentially zero compared to this value. 4-wire Case E looks similar. Since the PTs were connected to other power meters which were reading correctly, suspect two CT leads swapped. Since A-phase power factor is the only one that has a normal looking lagging value, suspect B and C-phase CT leads may be swapped. After swapping B and C-phase CT leads, all readings went to the expected values; problem solved.

The power meter registers can be used with MODBUS or JBUS protocols. Although the MODBUS protocol uses a zero-based register addressing convention and JBUS protocol uses a one-based register addressing convention, the power meter automatically compensates for the MODBUS offset of one. Regard all registers as holding registers where a 30,000 or 40,000 offset can be used. For example, Current Phase A will reside in register 31,100 or 41,100 instead of 1,100.

Floating-point Registers
Floating-point registers are also available. To enable floating-point registers, see “Enabling Floating-point Registers” on page 91.

How Date and Time are Stored in Registers
The date and time are stored in a three-register compressed format. Each of the three registers, such as registers 1810 to 1812, contain a high and low byte value to represent the date and time in hexadecimal. Table B–1 lists the register and the portion of the date or time it represents. Table B–1: Date and Time Format
Register
Register 0 Register 1 Register 2

Hi Byte
Month (1-12) Year (0-199) Minute (0-59)

Lo Byte
Day (1-31) Hour (0-23) Second (0-59)

Table B–2 provides an example of the date and time. If the date was 01/25/00 at 11:06:59, the Hex value would be 0119, 640B, 063B. Breaking it down into bytes we have the following: Table B–2: Date and Time Byte Example
Hexadecimal Value
0119 640B 063B

Hi Byte
01 = month 64 = year 06 = minute 19 = day

Lo Byte

0B = hour 3B = seconds

NOTE: Date format is a 3 (6-byte) register compressed format. (Year 2001 is represented as 101 in the year byte.)

How Signed Power Factor is Stored in the Register
Each power factor value occupies one register. Power factor values are stored using signed magnitude notation (see Figure B–2). Bit number 15, the sign bit, indicates leading/lagging. A positive value (bit 15=0) always indicates leading. A negative value (bit 15=1) always indicates lagging. Bits 0–9 store a value in the range 0–1,000 decimal. For example the power meter would return a leading power factor of 0.5 as 500. Divide by 1,000 to get a power factor in the range 0 to 1.000. Figure B–2: Power Factor Register Format
15 14 13 12 11 10 0 0 0 0 0 9 8 7 6 5 4 3 2 1 0

Sign Bit 0=Leading 1=Lagging

Unused Bits Set to 0

Power Factor in the range 100-1000 (thousandths)

When the power factor is lagging, the power meter returns a high negative value—for example, -31,794. This happens because bit 15=1 (for example, the binary equivalent of 31,794 is 1000001111001110). To get a value in the range 0 to 1,000, you need to mask bit 15. You do this by adding 32,768 to the value. An example will help clarify. Assume that you read a power factor value of -31,794. Convert this to a power factor in the range 0 to 1.000, as follows: -31,794 + 32,768 = 974 974/1,000 = .974 lagging power factor
