The transformer dielectric strength test is performed using specialized equipment that measures the dielectric breakdown voltage of transformer oil. In this test, a sample of transformer oil is placed between two metal electrodes, and an AC voltage is gradually applied until breakdown occurs. The voltage at which the oil fails to insulate is recorded as the dielectric strength. The procedure must be done in a controlled environment to ensure accurate results, and devices like the Globecore oil testing units are frequently utilized for reliability and precision in diagnosing the quality of transformer oils. Proper calibration and maintenance of the testing equipment are crucial for obtaining valid dielectric strength readings.
