WebAC current is calculated by the power factor of 0.86 for single-phase supply and 0.8 for three-phase supply. Look at the table the 1 hp motor takes will be 1.3 A at 440 Volts three-phase at the same time while using single-phase it takes only 3.8 Amps. Also 5 HP three-phase motor takes 6.4 Amps. WebThe phase current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts (V): I(A) = 1000 × P(kW) √3 × PF × VL-L(V) Calculation with line to neutral voltage DC amps to kilowatts calculation.
