in short circuit test of a transformer in which side supply voltage is applied?

In a short circuit test of a transformer, the supply voltage is applied to the low-voltage (LV) side. This test is conducted to determine the transformer’s impedance and losses under short-circuit conditions. The high-voltage (HV) side is left open, allowing the test to measure the current and voltage on the LV side while simulating a short circuit. This helps in assessing the transformer’s performance and efficiency.
