AC three phase kilowatts to amps calculation formula[/h] The current I in amps is equal to 1000 times the power P in kilowatts, divided by square root of 3 times the power factor times the voltage V in volts: I = 1000× P / (√3 × PF × V )
So amps are equal to 1000 times kilowatts divided by square root of 3 times power factor times volts.
amps = 1000×kilowatts / (√3 × PF × volts)
or
A = 1000 × kW / (√3 × PF × V)
[h=4]Example[/h] What is the current in amps when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the voltage supply is 110 volts? I = 1000 × 0.33kW / (√3 × 0.8 × 110V) = 2.165A
