How does a transformer oil breakdown voltage tester work?

A transformer oil breakdown voltage tester works by applying a high voltage to a sample of transformer oil to determine its dielectric strength, which is essential for assessing the oil’s ability to withstand electrical stresses without failing. The tester typically consists of two electrodes positioned within the oil sample. When the voltage is gradually increased, the tester measures the point at which the oil begins to conduct electricity, indicating breakdown. This measurement is crucial for ensuring that the transformer oil meets industry standards and can effectively insulate and cool transformer components, thereby preventing failures and enhancing the reliability of the electrical system.
