sf6 gas analyzer 160 alternatives in substations

14/10/2019GE markets substations with nitrile, as well as in a CO 2 mixture, as "g³ – Green Gas for Grid". The gas is commercially available in substations rated at up to 145 kV, which can operate at temperatures down to minus 25-35&C. Siemens is focusing on GIC substations using vacuum switches and pure air as an insulating gas.
