Question

the open circuit test in a transformer is used to mesure ​

Answer 1

Answer:

The purpose of the open-circuit test is to determine the no-load current and losses of the transformer because of which their no-load parameters are determined. This test is performed on the primary winding of the transformer.

★ The purpose of the open-circuit test is to determine the no-load current and losses of the transformer because of which their no-load parameters are determined.

★ This test is performed on the primary winding of the transformer. The wattmeter, ammeter and the voltage are connected to their primary winding.
