  • A review on SF6 substitute gases and research status of

    Nov 01, 2018SF 6 gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However, the application of SF 6 gas faces two serious problems, including the heavy global warming effect and high toxicity of its decomposition products. So, scholars committed to finding environmental-friendly alternative to SF 6 gas and the relevant research results have been obtained.

  • Optical technology for detecting the decomposition

    1. Introduction. Sulfur hexafluoride (SF 6) is a reliable insulating gas and has excellent arc-extinguishing properties.SF 6-insulated electrical equipment, such as switchgear, transformers, and lines, is widely used in city power grids and ultrahigh-voltage power transmission systems owing to its small footprint, high reliability, and long service life.

    The key difference between g3 and SF6 is that g3 is a gas mixture while SF6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “ The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process.
