Why should transformer oil have a high breakdown voltage?

Transformer oil should have a high breakdown voltage because it ensures effective insulation and minimizes the risk of electrical arcing, which can lead to equipment failure and safety hazards. A high breakdown voltage indicates the oil’s ability to withstand electrical stress without conducting electricity, thus maintaining the integrity of the transformer’s insulation system. This is crucial for the reliable operation of transformers, as any breakdown can result in short circuits, equipment damage, or potential fire hazards. Using a quality tester from Globecore can help accurately measure the breakdown voltage of transformer oil to ensure it meets industry standards and provides optimal performance.
