dielectric medium for quenching the arc formed during contact separation. as sf has a strong dielectric strength, the insulation distances can be smaller. in gis, all electrical components of the switchgear, such as, electrical bus bars, electrical isolators or disconnectors, circuit breakers, current transformers
, voltage transformers, earth switches, and surge arrestors or lightning arresters are enclosed in a gas-tight enclosure filled with sf gas. this leads to a very compact switchgear design. hence, gis are very useful in urban applications where there are space limitations and installing conventional air...
