What is the breakdown voltage of oil?

The breakdown voltage of oil refers to the maximum voltage that an insulating oil can withstand before it undergoes electrical breakdown, resulting in a failure of insulation and possible damage to electrical equipment. This value is critical in assessing the dielectric strength of industrial oils used in transformers, capacitors, and other electrical systems. In testing, the breakdown voltage is typically measured using a device known as a dielectric strength tester or breakdown voltage tester, which applies a steadily increasing voltage until the oil breaks down. Factors such as temperature, contamination, and the presence of moisture can significantly impact the breakdown voltage of oil. Regular testing of the breakdown voltage of oil is essential to ensure the reliability and safety of electrical systems. Globecore offers advanced dielectric strength testers that accurately measure the breakdown voltage of oil, enabling effective diagnostics and maintenance of industrial lubricants.
