The apparent power S in kilovolt-amps (kVA) is equal to the real power P in kilowatts (kW), divided by the power factor PF:
S = P / PF
Calculation with line to neutral voltage
The power P in kilowatts (kW) is equal to 3 times the FP times the phase currentI in amps (A), times the line to neutral RMS voltage V in volts (V) divided by 1000:
P = 3 × PF × I × V / 1000
