Correct Answer : Option (B) : Copper loss
Explanation : Short circuit test is conducted on the HV side of the transformer, where the LV side of the transformer is short-circuited. Afterward, a wattmeter is connected to the primary side of the transformer as well as an ammeter is connected in series with the primary winding of the transformer.
The total applied voltage for full load current in short circuit test on primary HV side of the transformer is quite low as compared to the rated voltage. With the help of this test, we get the total copper loss to happen in the transformer during full load condition.
