WebIt depends on load current, voltage and power factors. The kVA rating can be calculated using the following formula: For single phase transformers: kVA = (Load voltage x Load current) / (1000 x Load Power factor) For three phase transformer, kVA = (1.723 x Load voltage x Load current) / (1000 x Load Power factor) Try: Online kVA calculator WebApr 11, 2024 · The formula for both three-phase and single phase transformers is given below. 3 phase transformer current is equal to: I3ph = P3ph / (√3 × V3ph) Where: I3ph [kA] = the current flowing through the windings. P3ph [kVA] = the rated 3 phase power of the transformer. V3ph [kV] = the 3 phase voltage at the windings.
