Web14 aug. 2024 · The insulation resistance test of transformer is carried out by the megger, so it is also known as megger test of transformer. This test is performed to ensure the healthiness of the overall insulation of the transformer. The procedure of the insulation tests of transformer is as follows − WebMagnetic balance test of transformer is conducted only on three phase transformers to check the imbalance in the magnetic circuit. Test Instrument: Multi meter. Mill Ammeter Test Circuit Diagram: Test Procedure: First keep the tap changer of transformer in normal position. Now disconnect the transformer neutral from ground. WebThe magnetic balance test is usually done on the star side of a transformer. A two phase supply 440V is applied across two phases, say, 1U and 1V. The phase W is kept open. The voltage is then measured between U-V and U-W. The sum of these two voltages should give the applied voltage. That is, 1U1W + 1V1W will be equal to 1U1V. tiffany craftsmanship
