KVA, or kilovolt-ampere, is a unit of apparent power in an electrical system, representing the combination of both real power (kW) and reactive power (kVAR).

It's a crucial measure for assessing the total power demand in a system, considering both real and reactive components. Power factor, the ratio of real power to apparent power, is vital for evaluating system efficiency.

kVA to Amps Conversion Formula

The formula to convert kVA to amps involves the power factor (PF) and voltage (V). For both single-phase and three-phase systems, the formula can be expressed as:

Voltage Difference - Line to Line and Line to Neutral

In three-phase systems, it's important to consider both line-to-line (LL) and line-to-neutral (L-N) voltage differences. The voltage across a phase and the neutral is different from the voltage between two phases.

For line-to-line (LL) voltage

${V}_{LL}={V}_{Phase}×\sqrt{3}$

For line-to-neutral (L-N) voltage

${V}_{L-N}={V}_{Phase}$

Single-Phase kVA to Amps Formula

For a single-phase system, the formula simplifies to

$I\left(Amps\right)=\frac{S\left(kVA\right)}{V\left(Volts\right)×PF}$
