Power Meter Characteristics
The power meter measures currents and voltages and reports real-time RMS values for all 3-phases and neutral. In addition, the power meter calculates power factor, realpower, reactive power, and more.
The following sections list the metering characteristics of the power meter.

Real-Time Measuring
The following table lists the metering characteristics of the power meter for the real-time
measurement:
Characteristics Description
Current Per phase, neutral, and average of 3 phases
Voltage L-L, L-N, and average of 3 phases
Frequency 45...65 Hz
Active power Total and per phase (signed)
Reactive power Total and per phase (signed)
Apparent power Total and per phase(signed)
Power factor (True) Total and per phase
0.000 to 1 (signed)
Angle Voltage angle,Current angle
Current unbalance Per phase, most unbalanced of 3 phases
Voltage unbalance most unbalanced of 3 phases

Minimum/Maximum Values
When any one-second real-time reading reaches its highest or lowest value, the power meter saves the minimum and maximum values in its nonvolatile memory.
From the power meter display, you can:
• view all min./max. values since the last reset and the reset date and time.
• reset min./max. values.
All running min./max. values are arithmetic minimum and maximum values. For example, the minimum phase A-N voltage is the lowest value in the range from 0 to 999.9GV that has occurred since last reset of the min./max. values.
The power meter provides time stamping for all minimum/maximum values.
The following table lists the minimum and maximum values stored in the power meter:

 
Characteristics Description
Current Per phase and average
Voltage per phase and average
Active power Per phase and total
Reactive power Per phase and total
Apparent power Per phase and total

Demand Readings
The power meter provides the following demand readings.
 
Characteristics Description
