  • 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 quantities of the harmful gas.

  • SF6 Monitoring System - ENEIDA.IO

    SF6 is an inert gas mixture with excellent dielectric properties, and it has been widely applied on very high voltage parts such as Gas-Insulated Switchgears (GIS) in order to reduce its size or increase the working voltage. SF6 also has a high contribution for the Greenhouse Effect so its use is deeply regulated.

  • “Accessibly sealed” generation of GIS: what opportunities are

    Aug 21, 2019 · nuventura’s GIS, while keeping all the advantages of an SF6-based GIS, is based on dry air and allows for the tank to be “accessibly” sealed. This means that the GIS remains sealed and does not require any more maintenance than a traditional SF6-based GIS, but the core GIS tank can be accessed onsite to carry out remedial works if necessary.
