Buchholz Relay & Oil Surge Relay

Untitled 1

The Buchholz Relay is one of the most essential protective devices to protect equipment such as 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 aluminium alloy instead of casted CI body, in which micro cracks may give leakage at any time.
  • No need to treat for porosity, since no micro cracks 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.
  • Available in 3 sizes for pipe diameter:
    • 25 mm (GOR - 1)
    • 50 mm (GOR - 2)
    • 80 mm (GOR - 3)
  • Compact & hence, low weight design with high efficiency.
  • We also manufacture Oil Surge Relays for protection of O.L.T.C.
