In the Buchholz relay, the collected gas displaces the oil to an amount equal to the volume of gas collected. The upper float closes the upper mercury switch, which is coupled to an alert circuit, as a result of the displacement of oil.
WebThe Buchholz relay purpose is to give the protection to a transformer from the different faults happening in the transformer like the Short circuit, inter-turn, core, incipient, etc. This relay will sense these faults and shuts the … WebBuchholz relays operate based upon the amount of gas generated by small electrical faults, large electrical faults and the transformer insulating liquid level. General Faults General …
WebThe relay should be mounted in the connecting pipe between the transformer and the conservator tank. This pipe should be as long and as straight as possible, and must be arranged to slope upwards, towards the conservator, at an angle within the limits of 3 to 7 degrees to the horizontal. There should be a straight run on the transformer side of ...
