The purpose of oil in an electric transformer is to serve multiple essential functions, including insulation, cooling, and protection against electrical faults. The oil acts as an insulator to prevent electrical discharges between conductors and to maintain voltage levels. Additionally, it effectively dissipates heat generated during the transformer’s operation, ensuring optimal performance and preventing overheating that could lead to equipment failure. The oil also helps to prevent oxidation and moisture ingress, thereby protecting internal components from degradation and extending the transformer’s lifespan. Proper management, including regular testing and maintenance of the oil, is crucial to ensuring the reliability and efficiency of electric transformers.
