  • SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS

    Advantages of sulphur hexafluoride in gas-insulated switchgears. SF 6 insulation allows safe operation of high- and medium-voltage systems in close areas, since insulation with sulphur hexafluoride requires much smaller safety clearances. Non-dispersive infrared gas sensors (NDIR sensors) from smartGAS are ideal for measuring the SF 6 gas quality and for detecting even very small

  • Nanomaterials‐based gas sensors of SF6 decomposed

    It was found that phosphorene is quite inert in terms of interaction with SF 6 (E ad is −0.19 eV), which allows the selective detection of SF 6 decomposed species in the mixture gases. Besides, the surface possesses better adsorption ability upon SO 2 than H 2 S, with higher E ad and charge‐transfer in the former system (−0.382 and 0.118 eV) compared with those in the latter system (−0.208 and 0.047 eV).Cited by: 17
