What is Transformer Oil?
Transformer oil, also known as insulating oil, is a highly refined fluid used in electrical equipment such as transformers, circuit breakers, and switchgear. It serves two critical functions:
- Electrical Insulation – Prevents electrical discharges
- Cooling – Dissipates heat generated during operation
Additionally, it acts as a protective barrier against oxidation, extending the lifespan of transformer components.
