Buchholz relay in a transformer is an oil container housing the connecting pipe from the main tank to the conservator tank. The collected amount of gas indicates the severity of the fault occurred. Best Bosch Relay Wiring Diagram 5 Pole • Electrical Outlet Symbol 2018. Whenever a fault occurs inside the transformer, such as insulation failure of turns, breakdown of core or excess core heating, the fault is accompanied by production of excess heat. Buchholz relay is a gas-actuated relay installed in oil immersed transformers for protection against all kinds of faults. It is installed between the conservator and main tank. Gas bubbles tend to flow in upward direction towards conservator and hence they are collected in the buchholz relay which is placed on the pipe connecting the transformer tank and conservator. The identification numbering of the wiring diagrams follows criteria that allow to identify the type and approximate operation of the wiring diagram from it's number. It is a type of oil and gas actuated protection relay.
