The breakdown voltage of transformer oil is a critical parameter that indicates the oil’s insulating strength. Typically, the breakdown voltage of transformer oil should be above 30 kV for effective performance in power transformers. This value can vary based on the oil’s purity, moisture content, and presence of contaminants. Regular testing of the breakdown voltage is essential to ensure the reliability and safety of power transformers in operation.
