What is the purpose of an oil level indicator in a transformer?

The purpose of an oil level indicator in a transformer is to provide real-time monitoring of the oil level within the transformer tank, ensuring that the insulating oil remains at appropriate levels for optimal performance. This is crucial as the insulating oil serves to cool the transformer and insulate the internal components, preventing overheating and electrical discharges. By maintaining the correct oil levels, the oil in transformer name ensures effective operation, reducing the risk of faults and prolonging the transformer’s lifespan. Additionally, the oil level indicator assists in identifying any potential leaks or the need for oil replenishment, thus supporting maintenance and safety protocols.
