Transformer Sizing Calculator
To calculate a three-phase transformer''s load capacity, use the straightforward formula: kVA= Current × Voltage × √3 / 1000. Say your household load voltage is 2000V, and the load current is 250A. kVA= 250 × 2000 × √3 / 1000. kVA= 866025 / 1000. kVA = 866. For this load capacity, the suggested size of the transformer is 1000kVA.
