The following kVA to Amps conversion calculator will convert the apparent power also known as kilovolt amperes or kVA into current “I” in amperes “A”.
Formula for calculating amps from KVA using a Single Phase:
Current, measured in amperes, is proportional to the product of 1000 times the perceived power, measured in kilovolt-amperes, and voltage, measured in volts.
I = 1000 × kVA / V
Formula for calculating amps from KVA using a Three Phase:
Line-to-line voltage calculation:
When there are balanced loads, the phase current I in amps is equal to 1000 times 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 = 1000 × kVA / (√3 × VL-L)
Line-to-Neutral voltage calculation:
When balanced loads are present, the phase current I in amps is proportional to 1000 times the apparent power S in kilovolt-amps multiplied by 3 times the line to neutral RMS voltage VL-N in volts:
I = 1000 × kVA / (3 × VL-N)
