WebNov 12, 2024 · Simply multiply your known values together to find the answer. For example, with I = 50 A, V = 250 V and pf = 0.9, this gives: P = √3 × pf × I × V = √3 × 0.9 × 50 A × 250 V = 19,486 W Since this is a big number, convert to kW using (value in watts) / 1000 = (value in kilowatts). 19,486 W / 1000 = 19.486 kW WebIt is used to calculate the apparent power, power factor, correction capacitor's capacitance and the reactive power. You start by first selecting the phase which may be single or three phase. You need to enter the real power in Kilowatts, current in amps, the voltage in volts and frequency in hertz.
WebPower factor calculation: PF = cos φ = 1000 × P (kW) / (√ 3 × V L-L(V) × I (A)) Apparent power calculation: S (kVA) = √ 3 × V L-L(V) × I (A) / 1000. Reactive power calculation: Q … WebPower factor can be defined as the ratio of real power (Active power) to apparent power.
