Answer 1

The open-circuit test in a transformer is used to measure

Answer 2

Answer:

            The open circuit test in the transformer is used to measure the determine the core losses produced in the transformer and the parameters of the shunt branch which is connected equivalent to the transformer, to determine the losses of no-load current and no-load equivalent circuit. this test can be done on either primary winding or secondary winding.

INPUT AND OUTPUT POWER:

          During the open circuit test in a transformer their is zero output value because it is an open circuit. so, the input given is comes under core loss in transformer and as copper loss when connected to a no-load transformer.
