What is the open-circuit test in transformers?

I - It is also called the no-load test.

II - It is performed with the secondary open and the nominal voltage applied to the primary.

III - It is used to obtain the equivalent impedance in parallel.

IV - It is used to measure the applied voltage, open-circuit current, and power.
