  • Detection of partial discharge in SF6 gas using a carbon

    For electrical insulation diagnosis of gas-insulated switchgear (GIS), detection of partial discharge (PD) generated in sulfur hexafluoride (SF 6) gas is important. This paper describes a new detection method of PD generated in SF 6 gas using a gas sensor composed of multiwall carbon nanotubes (MWCNTs). The gas sensor was fabricated by electrokinetic manipulation of semiconducting MWCNTs using positive dielectrophoresis.

  • Sulphur Hexafluoride | Edinburgh Sensors | Gas Detection

    Sulphur Hexafluoride. NDIR sensors for measuring SF 6 leaks. Sulphur hexafluoride is an inorganic, colourless, odourless, non-flammable gas which is an excellent electrical insulator. It is an extremely potent greenhouse gas therefore it is important to minimise leaks of it to the environment. It absorbs strongly in the infrared, so NDIR sensors are ideally suited to detecting it at low ppm concentrations.
