What is the role of oil filled transformers in power systems?

The role of oil filled transformers in power systems is crucial for electrical insulation and cooling. The oil serves as an insulating medium, preventing electrical discharges, while also dissipating heat generated during operation. This enhances the transformer’s efficiency and longevity. Additionally, the oil helps in maintaining optimal operating temperatures, ensuring reliable performance in power distribution networks. Overall, oil filled transformers are essential for the safe and efficient operation of power systems.
