Select Phase: Single Phase Three Phase Apparent Power (KVA): Voltage (Volts): Select Connection: Line to Line Line to Neutral

 

Single phase kVA to amps calculation formula

The current I in amps is equal to 1000 times the apparent power S in kilovolt-amps, divided by the voltage V in volts:

I_(A) = 

1000 × S_(kVA)V_(V)

3 phase kVA to amps calculation formula

Calculation with line to line voltage

The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovolt-amps, divided by the square root of 3 times the line to line RMS voltage V_L-L in volts:

I_(A) = 

1000 × S_(kVA)√3 × V_L-L(V)

Calculation with line to neutral voltage

The phase current I in amps (with balanced loads) is equal to 1000 times the apparent power S in kilovolt-amps, divided by 3 times the line to neutral RMS voltage V_L-N in volts:

I_(A) = 

1000 × S_(kVA)3 × V_L-N(V)
