What is the breakdown voltage of transformer oil as detailed in the PDF?

The breakdown voltage of transformer oil is a critical parameter that indicates its 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 the presence of contaminants. Regular testing is essential to ensure that the breakdown voltage of transformer oil remains within acceptable limits for safe operation.
