Measuring partial discharge in GIS | Think Grid 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.
