Depending on the model, the relay has multiple methods to detect a failing transformer. On a slow accumulation of gas, due perhaps to slight overload, gas produced by decomposition of insulating oil accumulates in the top of the relay and forces the oil level down. A float switch in the relay is used to initiate an alarm signal. Depending on design, a second float may also serve to detect slow oil leaks. WebThe Buchholz relay is designed to detect these gas and oil flow disturbances and activate an alarm or trip signal to disconnect the transformer from the power source, thereby …
