Frequently Asked Questions: Regulation for Reducing Sulfur ...· PDF file1/22/2019· 1. Are all gas insulated switchgear (GIS) owners subject to this regulation, even if the GIS owner is not an electric utility? Yes. This regulation applies to all owners of GIS equipment that contains sulfur hexafluoride (SF 6). The regulation makes no distinction as to whether or not a GIS device is owned by an electric utility. 2.
Introduction to Gas Insulated Substations / Switchgears (GIS) various modules are factory assembled and are filled with SF6 gas. Thereafter, they are taken to site for final assembly. SF6 Gas Insulated Substations are compact and can be installed conveniently on any floor of a multi-storeyed building or in an underground substation.
