  • Gas Insulated Substation Control and Monitoring

    2020-10-15Most gas density monitors installed as part of the GIS are of the “relay” type. They use contact closures to signal that defined gas density thresholds have been reached. Visual displays on the devices themselves typically consist of color-coded status indicators, but do not give a quantifieddensity value. With this
