  • Gas Insulated Substation (GIS) Electrical Power System

    Apr 10, 2020Gas Insulated Substations. A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible.3.6/5(6)
