How do you check Buchholz operation?

Answer 1

To check the Buchholz relay operation, first ensure that the relay is properly installed on the transformer. Then, simulate a fault condition, such as tilting the transformer or using a test device to create gas or oil movement within the relay. Observe the relay's response; it should trigger an alarm or trip the transformer if gas accumulation or oil displacement occurs. Finally, reset the relay and check for any fault indications or alarms on the monitoring system.
