How do I convert Amps to kVA?
Calculation with line to line voltage
- S(kVA) = √3 × I(A) × VL-L(V) / 1000.
- So kilovolt-amps are equal to √3 times amps times volts divided by 1000.
- kilovolt-amps = √3 × amps × volts / 1000.
- kVA = √3 × A ⋅ V / 1000.
- S = √3 × 12A × 190V / 1000 = 3.949kVA.
What is 1kVA?
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.
What does 1.732 mean?
1.732 = a constant necessary with 3 phase. In a three phase circuit, the use of the constant 1.732 results from the fact that not all three phases are producing the same amount of power at the same time. Each phase’s voltage and current move through zero at different times.

How do you calculate amps per phase?
Divide the power consumption in watts by the line voltage multiplied by the power factor to find the amperage. For three phase circuits the power factor is the square root of 3. If your calculator doesn’t have a square root function, use 1.73 as an approximation of the square root of 3.
