Question

Accepted Answer

Buchholz relay is used to protect transformers from faults by detecting gas and oil flow abnormalities.

Buchholz relay is installed in the pipe connecting the transformer tank and conservator tank.
It operates based on the principle that faults in the transformer generate gases and cause oil flow disturbances.
When gas or oil flow abnormalities occur, the relay trips and sends a signal to the control panel to isolate the transformer.
It provides protection against faults such as internal short circuits, insulation failure, and overheating.
Regular maintenance and testing of the Buchholz relay are essential to ensure its proper functioning.
