Transformer oil is a highly refined mineral oil or synthetic oil used as an insulating and cooling medium in transformers, high-voltage capacitors, and circuit breakers. It plays a critical role in the efficient and safe operation of electrical equipment by providing insulation, preventing corona discharge, and dissipating heat.

Types of Transformer Oil:

  • Mineral-Based Transformer Oil: Commonly used in power and distribution transformers.
  • Synthetic Transformer Oil (Silicone-Based): Often used in indoor transformers or where fire safety is crucial.
  • Biodegradable (Natural Ester) Transformer Oil: Suitable for environmentally sensitive areas and applications requiring high fire safety.

Applications

  • Power Transformers: Used extensively in power transformers for insulation and cooling.
  • Distribution Transformers: Essential in distribution transformers for efficient operation and long service life.
  • Circuit Breakers: Used in oil-filled circuit breakers to quench arcs and prevent overheating.
  • High-Voltage Capacitors and Switchgear: Insulates and cools components in high-voltage systems.
