Single phase kVA to amps calculation formula

So 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)

Example 1

Question: What is the phase current in amps when the apparent power is 3 kVA and the RMS voltage supply is 120 volts?

Solution:

I = 1000 × 3kVA / 120V = 25A

Example 2

Question: What is the phase current in amps when the apparent power is 3 kVA and the RMS voltage supply is 150 volts?

Solution:

I = 1000 × 3kVA / 150V = 20A

3 phase kVA to amps calculation formula

Calculation with line to line voltage

So 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) )

Example 1

Question: What is the phase current in amps when the apparent power is 3 kVA and the line to line RMS voltage supply is 110 volts?

Solution:

I = 1000 × 3kVA / (3 × 110V) = 15.746A

Example 2

Question: What is the phase current in amps when the apparent power is 3 kVA and the line to line RMS voltage supply is 150 volts?

Solution:

I = 1000 × 3kVA / (3 × 150V) = 11.547A

Calculation with line to neutral voltage

So 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) )

Example 1

Question: What is the phase current in amps when the apparent power is 3 kVA and the line to neutral RMS voltage supply is 110 volts?

Solution:

I = 1000 × 3kVA / (3 × 110V) = 9.091A

Example 2

Question: What is the phase current in amps when the apparent power is 3 kVA and the line to neutral RMS voltage supply is 150 volts?

Solution:

I = 1000 × 3kVA / (3 × 150V) = 6.667A
