Ac method: apply 50Hz AC voltage between the low-voltage side of the tested transformer (such as generator, high voltage neutral point grounding). According to the power supply capacity, adjust the compensation capacitor C, reduce the power supply current, the low-voltage side of the test to reflect the average voltmeter Va readings, gradually increase the voltage to 50% rated voltage, and stay about 5 min. Slowly drop the voltage to "zero" and slowly raise the voltage again to 100% rated voltage until complete demagnetization.
