  • An Introduction to Gas Insulated Electrical Substations

    With GIS technology, the clearance needed for phase to phase or phase to ground for all equipment is much less than that of an AIS or air insulated substation . The total space required for a GIS is roughly a tenth of that needed for a conventional AIS facility. While the conventional, AIS requires several feet of air insulation to isolate
