Amps

Amps measure the motion of electricity as an electric current. Specifically, it measures the number of electrons that flow past a certain point per second.

Kilovolt-amp (kVA)

The unit KVA (kilovolt amperes) is a measure of the power in an electrical circuit.
1 kilo-volt-ampere is equal to 1000 volt-ampere.

Single phase kVA to amps calculation formula

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

I (A) = 1000 × P(kVA) / (√3 × VL-L(V) )

Calculation with line to neutral voltage

The phase current I in amps amp (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 VL-N in volts:
I (A) = 1000 × S(kVA) / (3 × VL-N(V) )
