What is the dielectric breakdown voltage of transformer oil?

The dielectric breakdown voltage of transformer oil is a crucial parameter that indicates its insulating properties and ability to withstand electric stress without failing. Generally, the dielectric breakdown voltage of transformer oil should be at least 30 kV for a solid performance, though higher values are preferred for enhanced safety and reliability in electrical systems. To accurately measure this voltage, you can utilize specialized testers designed by Globecore, which provide precise diagnostics of transformer oil’s insulating qualities. Regular testing is essential to maintain operational efficiency and prevent potential failures in transformers.
