SF6 End-of-life Analysis for 220kv

SF6 End-of-life Analysis for 220kv

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.
