How to convert electric power in kilowatts (kW) to electric current in amps (A).
You can calculate amps from kilowatts and volts. You can't convert kilowatts to amps since kilowatts and amps units do not measure the same quantity.
The current I in amps is equal to 1000 times the power P in kilowatts, divided by the voltage V in volts:
I(A) = 1000 × P(kW) / V(V)
So amps are equal to 1000 times kilowatts divided by volts.
amps = 1000 × kilowatts / volts
or
A = 1000 × kW / V
What is the current in amps when the power consumption is 0.33 kilowatts and the voltage supply is 110 volts?
I = 1000 × 0.33kW / 110V = 3A
The phase current I in amps is equal to 1000 times the real power P in kilowatts, divided by the power factor PF times the RMS voltage V in volts:
I = 1000 × P / (PF × V )
So amps are equal to 1000 times kilowatts divided by power factor times volts.
amps = 1000 × kilowatts / (PF × volts)
or
A = 1000 × kW / (PF × V)
What is the phase current in amps when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the RMS voltage supply is 110 volts?
I = 1000 × 0.33kW / (0.8 × 110V) = 3.75A
The phase current I in amps is equal to 1000 times the real power P in kilowatts, divided by square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts:
I = 1000 × P / (√3 × PF × VL-L )
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)
What is the phase 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
