Kilovolt-amps (kVA) to amps (A) calculator and how to calculate.

Enter phase number, the apparent power in kilovolt-amps, voltage in volts and press the *Calculate* button to get the current in amps:

### 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)}* *)
