DC kilowatts to amps calculation

The current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by the 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 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 V_L-L in volts (V):

I_(A) = 1000 × P_(kW) / (√3 × PF × V_L-L(V) )

Calculation with line to neutral voltage

The phase current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by 3 times the power factor PF times the line to neutral RMS voltage V_L-N in volts (V):

I_(A) = 1000 × P_(kW) / (3 × PF × V_L-N(V) )

Typical power factor values

Do not use typical power factor values for accurate calculations.
