What is the role of mineral insulating oil in transformers?

Mineral insulating oil in transformers plays a crucial role in electrical insulation and thermal management. It serves as an effective dielectric medium that prevents electrical discharges between conductive parts, ensuring safe operation. Additionally, this oil helps dissipate heat generated during transformer operation, enhancing the overall efficiency and lifespan of the equipment. Its high flash point contributes to fire safety, while its properties enable the filtering of moisture and particulates, maintaining a clean operating environment. Regular maintenance, including cleaning and regeneration of mineral insulating oil in transformers, is vital to uphold its performance and reliability over time.
