Amps to VA :
- Amps is a short form of ampere.Amp is the base unit of electrical current in the International System of Units (SI).
- A volt-ampere (VA) is a measurement of power in a direct current (DC) electrical circuit.
- The VA specification is also used in alternating current (AC) circuits, but in this case, it represents apparent power (represented in VA), which often differs from true power (represented in watts).
- In DC circuits, VA and watts (W) are equal.
Single Phase Amps to VA :
- S (VA) = I (A) x V (V).
- Which means that the apparent power in volt-amps is calculated by multiplication of the current in amps times the voltage in Volts.
Three Phase Amps to VA :
- S (VA) = √3 x I (A) x V L-L (V) = 3 x I (A) x V L-N (V).
- Which means that the apparent power in Kilovolts-amps, is calculated by multiplying the square root of three by the current in amps.Then multiplying by the line to line voltage in Volts.
