What is an oil-filled power transformer?

An oil-filled power transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction, utilizing oil as an insulating and cooling medium. The oil serves to dissipate heat generated during operation, ensuring the transformer operates efficiently and safely. Commonly used in substations and distribution systems, these transformers are designed to withstand a range of environmental conditions, offering durability and reliability. The insulating properties of the oil prevent electrical discharges, while its high heat capacity allows for effective cooling. Regular maintenance, including oil cleaning, regeneration, and testing, is crucial to ensure optimal performance and longevity of oil-filled power transformers.
