WebApr 24, 2006 · A 75 kVAR capacitor will improve the system power factor from 80% to 97%. Assuming that the motors is operating at 480 volt, 3 phase, the total current in the system would drop from 226 amps (187.5 kVA / .831) to 186 amps (154.6 kVA / 0.831), a total reduction of approximately 40 amps. WebThe following are useful formulas and equation while calculating the power factor, active power, reactive power and apparent power. Power Factor = Cosθ = Active Power/ Apparent Power; P.F = Cosθ = kW / kVA; kW = √ (kVA 2 – kVAR 2) kVA = √ (kW 2 + kVAR 2) kVAR = √ (kVA 2 – kW 2) Where: kW = Active Power = P = V x I x Cosθ
