sf6 gas insulated switchgear leak rate for 220kv

sf6 gas insulated switchgear leak rate for 220kv

The steel box is made gas tight. The use of SF6 circuit breaker is mainly in the substations which are having high input KV, say above 220KV and more. The gas is put inside the circuit breaker by force i.e. under high pressure. When if the gas gets decreases there is a motor connected to the circuit breaker.
