• The Transformer Buchholz Relay is one of the essential protective devices to protect equipment such as the transformer, capacitors, on-load tap changers, etc. It detects abnormal working of the components inside the equipment and consequently minimizes the spread of any damage to the equipment active part by disconnecting faulty apparatus before large-scale damage occurs to the apparatus or other connected apparatus.

Exclusive Features of our Buchholz Relay & Oil Surge Relay:

• Body is made of single piece die-cast aluminum alloy instead of casted CI body, in which microcracks may give leakage at any time
• No need to treat for porosity, since no microcracks are developed
• With mercury or magnetic reed switch; NO or NC contact as required
• Built-in test facility for checking continuity of both - alarm and trip circuits
