For single phase kVA calculations or conversions we need to know two of the three values of kVA, Volts and Amps. Calculations could be kVA from Amps and Volts, Amps from kVA and Volts or Volts from kVA and Amps. For three phase kVA calculations we also need...
...to know the Power Factor and kW values. There are a number of kVA formulas which maybe difficult to remember them all, in which case you may like to download our free kVA calculator app, see the details at the bottom of this page.
kVA Single Phase Calculations
To convert kVA to Amps we use this formula (single phase)
