What is an oil-immersed power transformer?

An oil-immersed power transformer is a type of transformer that uses insulating oil as a coolant and insulator, allowing it to operate efficiently under high voltage and heavy loads. The oil assists in heat dissipation, which enhances the transformer’s performance and longevity. This type of transformer is commonly used in electrical power distribution systems, including oil immersed distribution transformers, to ensure safe and reliable operation. The insulating oil also plays a crucial role in preventing arcing and flashovers between live components, thereby enhancing the overall safety of the electrical system. Regular maintenance, including cleaning and regeneration of the oil, is essential to prevent oxidation and ensure optimal performance of oil-immersed power transformers.
