Gas relays are intended for protection of oil-filled devices — transformers, autotransformers and the shunting reactors — from the internal damages which are followed by liberation of gas, decrease in level of oil from a tank in a dilator. It is known what the only protection reacting to a number of dangerous damages in a tank of the protected device is gas. Jet relays are used to protection of contactors of oil-filled switches of branches of transformers and autotransformers against the damages which are followed by emergence of the accelerated oil stream from a tank in a dilator.
