How does an oil burner transformer tester function in relation to transformer oil in power transformers?

An oil burner transformer tester functions by applying a high voltage to the transformer oil in power transformers to assess its dielectric strength and insulation properties. This testing method helps identify any degradation or contamination in the transformer oil, which can affect the overall performance and safety of the power transformer. By evaluating the oil’s ability to withstand electrical stress, maintenance can be effectively planned to ensure reliable operation.
