  • SF6 concentration sensor for gas-insulated electrical

    Feb 01, 2014The use of SF 6-N 2 gas mixtures in gas insulated electrical switchgear (GIS) is becoming more wide-spread. This is motivated by the reduction of environmental impact associated with SF 6 emission and the increasing number of GIS located in low temperature environments where pure SF 6 cannot be employed. We present a cost-efficient sensor system that tracks gas composition basedCited by: 6

  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF 6 Gas Density Sensors, or by combining both principles, i.e.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.

  • Gas density of SF6 and other gases - Trafag AG

    Gas Density Sulphur hexafluoride (SF6) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties. It thus makes it possible to set-up complex and safe power distribution systems even in large cities. The insulation strength depends basically on the gas density.
