Answer Posted / diwakar
there are two levels,in the first level if the level of oil
is decreased then it sends an alarm signal to the
operator,if the operator ignores then the gas formation in
the bank of relay increases then he second level of
protection is activated as it isolates the transformer.by
formation of gas in chamber they test the gas and conforms
where actual fault occured
