What is the function of an oil transformer bushing?

The oil transformer bushing serves as an essential component that facilitates the electrical connection between the transformer and its external environment, while simultaneously providing insulation. It houses the conductor that connects to the transformer windings and allows high voltage to pass through while effectively preventing any electrical leakage. Additionally, the bushing is filled with insulating oil which aids in cooling and dissipating heat generated within the transformer during operation. Maintaining appropriate oil levels and monitoring the oil temperature indicator in transformer applications is crucial for optimal performance and to ensure the bushing operates within safe temperature limits, preventing any risk of failure or damage to the transformer.
