How is the applied voltage test for a transformer conducted?

The applied voltage test transformer is conducted by connecting the transformer to a test source that applies the specified test voltage. The procedure involves ensuring that the transformer is isolated and properly grounded. Measurements are taken to verify that the insulation is intact and that there are no unexpected current flows. The voltage is typically increased to predetermined levels while monitoring for any signs of electrical breakdown or insulation failure. Proper safety protocols must be in place to ensure the test is performed safely and accurately, with results recorded for assessment of the transformer’s condition.
