kVAR = (kVA) (sinϕ)
Where,
kVA = Apparent power (S)
kW = Active/True power (P)
kVAR = Reactive power (Q)
cosϕ = Power factor
In an A.C. circuit, true power drawn by the circuit is given by:
True power = Apparent power × Power factor.
Calculation:
Here, input apparent power is 40 kVA and the power factor is 0.8
The power drawn by the circuit is:
(40 × 0.8) kW = 32 kW
