How does oil in transformers provide fire protection?

Oil in transformers provides fire protection through its high flash point and insulating properties. Transformer oil acts as a coolant, dissipating heat generated during operation, which reduces the risk of overheating and potential ignition. Additionally, the oil forms a barrier that can help suppress flames in the event of a fault, thereby enhancing the overall fire safety of the transformer system. Proper maintenance of oil quality is crucial for effective fire protection.
