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 VL-L in volts:
I(A) = 1000 × S(kVA) / (√3 × VL-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 VL-N in volts:
I(A) = 1000 × S(kVA) / (3 × VL-N(V) )
