Conditions for Open-Circuit Test:
First and foremost, it is important to understand that the open-circuit test is typically performed on the high-voltage (H.V) side of the transformer.
Leakage Impedance:
- One of the conditions that must be ensured for an open-circuit test is that the leakage impedance of the transformer can be obtained from this test. This helps in evaluating the leakage reactance of the transformer.
Magnetizing Impedance:
- Another important condition for the open-circuit test is that it provides the magnetizing impedance of the transformer. This helps in determining the magnetizing current required for the core to establish the magnetic flux.
In summary, the correct conditions for an open-circuit test are to perform it on the high-voltage side of the transformer and ensure that the leakage impedance and magnetizing impedance can be obtained from the test.

Leakage impedance is not found from open-circuit test. And it is performed on the rated voltage to account for core losses.
