How to convert apparent power in kilovolt-amps (kVA) to real power in kilowatts (kW).
The real power P in kilowatts (kW) is equal to the apparent power S in kilovolt-amps (kVA), times the power factor PF:
P(kW) = S(kVA) × PF
So kilowatts are equal to kilovolt-amps times the power factor.
kilowatts = kilovolt-amps × PF
or
kW = kVA × PF
What is the real power in kilowatts when the apparent power is 3 kVA and the power factor is 0.8?
Solution:
P = 3kVA × 0.8 = 2.4kW
