What is transformer oil breakdown voltage, and how does silicone oil influence it?

Transformer oil breakdown voltage is the measure of the oil’s ability to withstand electrical stress without failure. It indicates the maximum voltage the oil can tolerate before an electrical discharge occurs through it. Silicone oil, with its high dielectric strength, enhances the breakdown voltage of the transformer oil system. This means that the transformer can operate safely at higher voltages, reducing the risk of insulation failure and improving overall electrical performance.
