Active power in the network at the location of the CTs
P > 0: Load absorbing active power
P < 0: Load generating active power
Reactive power in the network at the location of the CTs
Q > 0: Inductive reactive power
Q < 0: Capacitive reactive power
Apparent power in the network at the location of the CTs
Power factor: calculation based on the fundamental and the
harmonic values of the measurements. Measurement only valid
for quasi-balanced loads.
Displacement power factor: calculation based on the
fundamental values of the measurements.
