Your meter provides bi-directional, 4-quadrant, revenue accurate energy metering:
•
kWh, kVARh, kVAh delivered and received
•
kWh, kVARh, kVAh net (delivered - received)
•
kWh, kVARh, kVAh total (delivered + received)
•
Volt-squared-hours and amp-squared-hours
•
Integration of any instantaneous measurement
Energy parameters can be logged automatically on a programmed schedule.
All energy values represent the total for all three phases.
Your meter supports several demand calculation methods, including block, rolling
block, synchronized and predicted demand.
It can measure demand on any instantaneous value and record peak (maximum)
demand with time and date information.
•
kW, kVAR, kVA demand
•
kW, kVAR, kVA peak demand
•
Amps, Volts demand
Your meter provides one second and half-cycle true RMS readings.
Instantaneous readings include:
•
3-phase voltages (line-to-line, line-to-neutral): per phase and average
•
Line-to-earth voltages per phase and V4, neutral-to-earth voltage
•
3-phase currents: per phase and average
•
I4 and I5 currents, measured
•
Residual current, calculated (I calc res)
•
Active (kW), reactive (kVAR) and apparent (kVA) power: per phase and total
•
Power factor per phase and total
•
System frequency
•
Voltage and current unbalance
•
Phase reversal
Your meter provides harmonic distortion metering, recording and real-time values
for all voltage and current inputs.
•
Individual harmonics (including magnitude, phase angle phase and inter-
harmonics) up to the 63
•
Total even harmonic distortion (TEHD), total odd harmonic distortion (TOHD)
•
Total harmonic distortion (THD), total demand distortion (TDD)
•
K-factor, Crest factor
