Answer Posted / deepak vats
Boucholz relay is a device which is used for the protection
of transformer from its internal faults, it is a gas based
relay.
whenever any internal fault occurs in a transformer, the
boucholz relay at once gives a horn for some time, if the
transformer is isolated from the circuit then it stop its
sound itself other wise it trips the circuit by its own
tripping mechanism
