  • Laois-Kilkenny Reinforcement Project

    An Air Insulated Switchgear substation (AIS substation) uses atmospheric air as the phase to ground insulation for the switchgear of an electrical substation. The main advantage of the AIS substation is the scope of the substation for future offloading, for this reason AIS substations tend to be the most popular 400kV substation type. The

  • The history of gas-insulated substations | Think Grid

    SF 6 gas was already known during the 1940s. Westinghouse holds the original patent for the use of SF 6 as interrupting medium, and their engineers developed the first applications for switches and circuit breakers in the early 1950s. In the 1960s all major manufacturers such as BBC-Calor Emag, Siemens, Magrini, Merlin-Gerin, NEI-Reyrolle, the Japanese and Delle-Alsthom had started intensive

  • Measuring partial discharge in GIS | Think Grid

    As a consequence, a GIS is much more compact. In fact, gas-insulated substations can be down to one-tenth the size of their air-insulated cousins, depending on the voltage level. The use of gas insulation in the power system network has developed rapidly thanks to its compact nature, low maintenance requirement and reliable operation.
