pipework between the top of the transformer main tank and the conservator. A second relay is sometimes used for the tapchanger selector chamber. The function of the relay is to detect an abnormal condition within the tank and send an alarm or trip signal. Under normal conditions the relay is completely full of oil. Operation occurs when floats are displaced by an accumulation of gas‚ or a flap is moved by a surge of oil. Almost all large oil-filled transformers are equipped with a Buchholz relay
