Watts to kVA calculation
The apparent power S in kilovolt-amps (kVA) is equal to the real power P in watts (W), divided by 1000 times the power factor PF:
S(kVA) = P(W) / (1000 × PF)
The apparent power S in kilovolt-amps (kVA) is equal to the real power P in watts (W), divided by 1000 times the power factor PF:
S(kVA) = P(W) / (1000 × PF)
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
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)
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) )
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) )
