Kilovolt-amp (kVA)

kVA is kilo-volt-ampere. kVA is a unit of apparent power, which is electrical power unit.

1 kilo-volt-ampere is equal to 1000 volt-ampere:

1kVA = 1000VA

1 kilo-volt-ampere is equal to 1000 times 1 volt times 1 ampere:

1kVA = 1000⋅1V⋅1A

kVA to volt-amps calculation

The apparent power S in volt-amps (VA) is equal to 1000 times the apparent power S in kilovolt-amps (kVA):

S_(VA) = 1000 × S_(kVA)

kVA to kW calculation

The real power P in kilowatts (kW) is equal to the apparent power S in kilovolt-amps (kVA), times the power factor PF:

P_(kW) = S_(kVA) × PF

kVA to watts calculation

The real power P in watts (W) is equal to 1000 times the apparent power S in kilovolt-amps (kVA), times the power factor PF:

P_(W) = 1000 × S_(kVA) × PF

kVA to amps calculation

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) )
