Gas operated Bucholz relay.

through it, gas bubbles are formed inside it.After the
formation of gases, immediately the relay gets operated &
it will sense the gas which gets build inside the
transformer. These gases are harmful and which switchoff
the transformer. This relay sense the gas & trip off the
transformer before a fault is occured
