  • Introduction to Gas Insulated Substations / Switchgears (GIS)

    In a GIS substation, the various equipment like Circuit Breakers, Bus bars, Isolators, Load break switches, Current transformers, Voltage transformers, Earthing switches, etc. are housed in separate metal-enclosed modules filled with SF6 gas.The SF6 gas provides the phase to ground insulation. Gas insulated switchgear parts. As the dielectric strength of SF6 gas is higher than air, the
