DC kilowatts to amps calculation

The value of current I in amps (A) is apparently equal to 1000 multiplied by the value power P measured in kilowatts (kW), and divided by the value voltage V in volts (V).

I(A) = 1000 × P(kW) / V(V)

AC single phase kilowatts to amps calculation

The phase current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by the power factor PF times the RMS voltage V in volts (V).

I(A) = 1000 × P(kW) / (PF × V(V) )

AC three phase kilowatts to amps calculation

Calculation with line to line voltage

The value of phase current I in amps (A) can be calculated easily as it is equal to 1000 times the value of power P in kilowatts (kW), which is divided by the square root of 3 multiplied by the power factor PF  multiplied by the line to line RMS voltage VL-L  measured in volts (V).

I(A) = 1000 × P(kW) / (√3 × PF × VL-L(V) )

Calculation with line to neutral voltage

The value of phase current I in amps (A) is apparently equal to the 1000 times the value of power P measured in kilowatts (kW), which is divided by thrice the power factor PF times the line to neutral RMS voltage VL-N measured in volts (V).

I(A) = 1000 × P(kW) / (3 × PF × VL-N(V) )
