Description

Transformer oils serve several essential functions within electrical transformers:

• Insulation: The primary function of transformer oils is to provide electrical insulation between the transformer’s live parts, such as the windings and core, and the grounded tank. This insulation prevents short circuits and ensures the safe and efficient operation of the transformer.
• Heat Dissipation: Transformer oils also act as coolants, dissipating heat generated during operation. This helps regulate the temperature of the transformer and prevents overheating, which can lead to reduced efficiency and premature failure.
• Arc Quenching: In the event of a fault or electrical discharge within the transformer, the oil acts as a medium to quench the arc and extinguish the resulting fire. This property is crucial for maintaining the safety of personnel and preventing damage to the transformer.
• Corrosion Protection: Transformer oils help protect the internal components of the transformer from corrosion by forming a barrier between metal surfaces and moisture or contaminants present in the environment.
