  • The basics of Gas Insulated Substation (GIS) for students

    Nov 22, 2018The grounding and disconnect switches, needed in both air and gas insulated arrangements, will have view ports in gas isolated devices. GIS has a reduced “footprint” than a corresponding air insulated substation, usually less than half the area. Even though a gas isolated substation will initially cost more than a similar air insulated substation, the economics may
