Buchholz Relays
P&B Weir Electrical has been a leading manufacturer of Transformer protection relays of the Buchholz principle for over 60 years. Most faults in an oil filled Transformer are accompanied by the generation of gas. By using a suitable relay the formation of this gas can be used as a warning of a developing fault.


Scope
Products have been designed, tested and manufactured to meet the detailed requirements of British Standard BEBS T2, Eskom and DIN specifications.

P&B Weir Electrical were also privileged to be represented on the technical committee responsible for preparation of the harmonised European specification EN 50 216, which relays also comply to.

Product Range
A vast range of standard products is available, whilst we are happy to provide units to your specific requirements e.g. fixings, flanges, conduit entry, calibration, finish etc.
