Transformer oil serves several crucial functions:
- Insulation: It provides electrical insulation between the internal components of the transformer, preventing short circuits.
- Cooling: The oil dissipates heat generated during transformer operation, maintaining optimal operating temperatures.
- Moisture Protection: It acts as a barrier against moisture, which can degrade the insulating properties of the transformer’s internal components.
- Arc Suppression: During faults, the oil helps quench arcing by providing a medium that can withstand high temperatures and electrical stress.
