  • PGE Phases Out SF6 in HV Substation GIS | TD

    10 mins readJan 27, 2020In addition to the cost to repair SF 6 leaks, vendor A equipment requires a biennial application of silicon grease to the flange joint and replacement of the flange O-ring seal after 10 years of service to maintain the design leak rate of 1%. At two newly installed GIS, using equipment installed and manufactured by vendor A, most of the flanges were found to be leaking SF 6 in excess of PGE’s

  • Gas-Insulated Substations - GIS - Energy and Power For All

    Standards now require GIS to leak less than 1% per year. The leakage rate is normally much lower. Field checks of GIS in service for many years indicate that the leak rate objective can be as low as 0.1% per year when GIS standards are revised.

    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.
