Current - Primary and Secondary
Metered current includes primary and secondary phase currents (IA, IB, IC), ground current (IG), positive-
sequence current (I1), negative-sequence current (I2), and neutral current (3I0). All current
measurements are auto ranging.
Values are provided for CT circuit 1 and CT circuit 2 (for protection systems equipped with two sets of
CTs).
Primary and secondary current metering data is found in BESTCOMSPlus (Figure 30-3) and on the
Metering > Analog Metering > Current screen of the front-panel display. A phasor diagram is also
provided in BESTCOMSPlus.

Power
Power metering data is found in BESTCOMSPlus (Figure 30-4) and on the Metering > Analog Metering >
Power screen of the front-panel display. A phasor diagram is also provided in BESTCOMSPlus.
Real Power
Real power is metered over a range of –4,500 kilowatts to +4,500 kilowatts on five-ampere nominal
systems. One-ampere nominal systems meter real power over a range of –900 watts to +900 watts.
Phases A, B, C, and total phase are included.
