What is an oil breakdown voltage tester?

An oil breakdown voltage tester is a specialized device used to measure the dielectric strength of industrial oils, particularly transformer oil. This instrument determines the voltage at which the oil breaks down, indicating its insulation properties and ability to withstand electrical stress. Globecore offers advanced testing equipment that can evaluate the purity and dielectric strength of transformer oil, ensuring that it meets the necessary standards for safe operation in electrical systems. Proper testing is essential, as the dielectric strength is a critical factor in the performance and longevity of transformers. What is minimum dielectric strength of transformer oil? The minimum dielectric strength required for transformer oil is typically 30 kV (kilovolts) per 2.5 mm gap, but higher values are preferred for optimal performance and reliability.
