SF6 generator circuit-breaker system for short-circuit currents up to 200 kA Lukas Zehnder, Jochen Kiefer, Dieter Braun, Thomas Schoenemann Generator circuit-breakers are the 'big boys' of the breaker world; they have to be. A fault of up to 200 kA somewhere in the field is bad enough, but close to a generator it can lead to an event of .
A non-inflammable gas. SF6 is an inert gas and does not sustain combustion. The seal and the for-life lubrication of the rotary seals is provided by an oil film. In the MV circuit breaker field, for example, on more than 20000 SF6 switchgears units insatlled by the French electical utility (EDF)
