THREE PHASE/A/B/C REAL POWER:
The total RMS three phase real power as well as the
individual phase A/B/C real power is displayed in these messages. The phase A/B/C real
power messages will be displayed only for a WYE or 3 WIRE DIRECT connected system. The
PQM shows direction of flow by displaying the signed value of kW. Refer to Figure 5.6 for
the convention used to describe power direction.
THREE PHASE/A/B/C REACTIVE POWER:
The total RMS three phase reactive power as well
as the individual phase A/B/C reactive power is displayed in these messages. The phase A/
B/C reactive power messages will be displayed only for a WYE or 3 WIRE DIRECT connected
system. The PQM shows direction of flow by displaying the signed value of kvar. Refer to
Figure 5.6 for the convention used to describe power direction.
THREE PHASE/A/B/C APPARENT POWER:
The total RMS three phase apparent power as
well as the individual phase A/B/C apparent power is displayed in these messages. The
phase A/B/C apparent power messages will be displayed only for a WYE or 3 WIRE DIRECT
connected system.
