•  Convert 1-Phase Watts Loss to 1-Phase kW by dividing the 1-Phase Watts Loss 

by 1000.

4. Enter 3-Phase MVA or 1-Phase MVA values. 

•  If 3-Phase MVA values are entered, calculate 1-Phase MVA values by dividing 3-

Phase MVA values by three. 

•  Convert 1-Phase MVA to 1-Phase kVA by multiplying by 1000.

5. Enter the % Exciting Current and % Impedance values.

6. Enter the Phase-to-Phase values for Test Voltage (Volts) and Full Load Currents 

(Amps). Note that Test Voltage is generally Phase-to-Phase for 3-Phase transform-
ers. 

a. Calculate Phase-to-Neutral Test Voltage by dividing Phase-to-Phase Test Voltage 

by the square root of 3. 

b. Calculate Full Load Current (Amps) by dividing the 1-Phase kW self-cooled rating 

by the Phase-to-Neutral Voltage and multiplying by 1000.
