What is the function of transformer oil?

The function of transformer oil is critical in ensuring the efficient operation of transformers. It serves as an insulating medium, preventing electrical discharge and maintaining dielectric strength between live parts and the ground. Additionally, transformer oil acts as a coolant, dissipating heat generated within the transformer, thus aiding in temperature regulation. It also plays a crucial role in preventing oxidation and moisture ingress, which can compromise the performance and longevity of the transformer. Furthermore, transformer oil helps in the maintenance of a stable environment, allowing for the safe and reliable operation of electrical equipment.
