The dielectric strength of transformer oil is typically expected to be in the range of 30 to 70 kV for a 2.5 mm gap, depending on the oil’s quality and condition. It is crucial to maintain this dielectric strength to ensure safe and effective operation of transformers, as low dielectric strength can lead to electrical breakdown and equipment failure. Regular testing using semiautomatic or fully automatic testers, like those from Globecore, is recommended to assess the dielectric strength of transformer oil in kV and ensure optimal performance.
