buccholz relay is a gas-actuated(usually) relay used to
detect internal faults in a trf. It consists of two sets of
mercury floats. when faults occur inside the trf( in paper
insulation, in oil etc.) gases are produced that move the
floats to actuate an alarm ckt.
it fault not rectified quickly, ultimately it causes the
trf ckt to be tripped
