Question

Q4. Short circuit test on transformers conducted to determine​

Answer 1

$\large \sf \: Answer:- \:$

Short circuit test is used to determine the copper losses taking place in the transformer under operation, while open circuit test gives us the value of core losses taking place in the transformer.

Answer 2

Answer:

short-circuit test for determination of transformer impedance and losses is carried out with relatively low power applied to the transformer, and with winding currents of the same magnitude as in operation.
