  • Gas Insulated Substation (GIS) Advantages - Disadvantages

    Jan 02, 2014Gas Insulated Substation has gas monitoring system. Gas inside each compartment should have a pressure of about 3kg/cm 2.The gas density in each compartment is monitored. If the pressure drops slightly, the gas is automatically trapped up. With further gas leakage, the low pressure alarm is sounded or automatic tripping or lock-out occurs.
