    2021-3-11. Introduction. Sulfur hexafluoride (SF 6) gas has been used as an arc extinguishing medium in gas-insulated switchgear (GIS) due to its excellent arc extinguishing performance, insulating properties, and good chemical stability , , .However, partial discharge happens in gas-insulated equipment as time goes, resulting in the decomposition of SF 6 (products: SO 2 F 2, H 2 S, SO 2, HF, etc.) , .Author: Shiying Guo, Xuemin Hu, Yong Huang, Wenhan Zhou, Hengze Qu, Lili Xu, Xiufeng Song, Shengli Zhang, Ha...

  • sf6 gas Gas Mixture monitor for Substation

    SUBSTATIONS The Challenge Direct leak detection in enclosed GIS substation requires highly sensitive and reliable SF 6 gas detection. GIS insulated switchgear require specific operation maintenance procedures to prevent and limit the emissions of the insulating gas (SF 6 – sulfur hexafluoride), which is a very potent greenhouse gas.

  • Health index and risk assessment models for Gas Insulated

    2020-5-1The failure rate of Gas Insulated Switchgear (GIS) operating under tropical conditions is about twice the value reported by the third CIGRE’s survey in 2007. Three major failure modes that lead to catastrophic failure of a GIS in tropics are the insulation breakdown, the primary joint-conductor failure, and the driving mechanism failure.

  • 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.
