    The switching necessary to isolate a breaker to add SF6 can be done without dropping load. Any breaker that goes from low to low-low faster than we can get gas added to it is probably loosing gas too fast to safely trip below the point at which it is no longer safe to allow the breaker to trip.

An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
