Use the 3 phase and single phase transformer sizing calculator below to calculate primary and secondary full load current. This can also be used as a transformer kVA calculator and transformer secondary short circuit current calculator. Calculator can be used for step down transformer as well as step up transformer sizing applications.
TRANSFORMER VOLTAGE DROP CALCULATOR
Transformer secondary side voltage drop calculation under load and various load power factor. Voltage drop due to transformer impedance can be calculated. User can select the transformer impedance.
TRANSFORMER REACTIVE POWER LOSS CALCULATOR
The calculator below can be used to calculate reactive power consumption in transformer at full load and rated voltage. To calculate the reactive power due to just the shunt magnetizing impedance, use %load as ‘No Load’.
