    Substation and switchgear techs: GIS is seen everywhere ...· However, SF6 is a greenhouse gas necessitating SF6 filled equipment being closely monitored for leaks. For this reason, GIS buses have built-in monitors and alarms to alert operators when leaks occur. It is also common to use thermal imaging, i.e. infra-red cameras, to detect leaks. In addition to switchgear,transformers are now using SF6 as well.
