C. core losses
D. eddy current losses
This Answer Is B
The short circuit test is an essential part of transformer testing. It is conducted to determine the winding resistance, reactance, and copper losses of the transformer.
By conducting this test, it is possible to calculate the copper losses at any desired load and the total voltage drop of the transformer referred to either the primary or secondary side. The circuit for a short circuit test involves applying a certainly impressed voltage at the rated current to measure the full load copper loss. This test can also be used to obtain the equivalent resistance and leakage reactance of the transformer.
