    Gas accumulation: Free gas is present in the transformer oil. Response: The gas in the liquid rises and accumulates in the Buchholz relay, compressing the transformer oil. As the liquid level drops, the float also descends. The movement of the float drives a switch element (magnetic contact), thereby triggering an alarm signal. However, the float is not affected, because a certain amount of gas can flow through the pipe into the storage chamber.Fault: Due to leakage causing loss of transformer o
