What is the breakdown voltage value for transformer oil?

The breakdown voltage value for transformer oil is a crucial parameter that indicates the oil’s insulation strength and its effectiveness in preventing electrical discharges. Generally, a breakdown voltage of at least 30 kV is considered satisfactory for transformer oils, although higher values can be expected and are ideal for ensuring optimal performance. It’s important to regularly test this parameter using specialized equipment like Globecore’s oil testing devices to monitor and maintain transformer oil quality, ensuring reliability and longevity in power systems.
