1408-EM3.
Metered Parameters
The power monitor calculates and returns four-quadrant power measurements including these:
•
L1, L2, L3 and Total True Power Factor, percent lagging (-) and leading (+)
•
L1, L2, L3 and Total Real Power, kW
•
L1, L2, L3 and Total Reactive Power, kVAR
•
L1, L2, L3 and Total Apparent Power, kVA
Only total three-phase power results are provided when Direct Delta or Open Delta wiring
modes are selected.
The
Magnitude and Direction of Power Quantities
chart indicates the relationship between the
magnitude and direction of the power quantities and the numeric signs used by the power
monitor.
