  • SF6 gas in medium-voltage switchgear | TD Guardian

    The process is reversible, so that nearly all of the SF6 recombines after interruption. Thus, very little of the SF6 is used up during interruption, particularly for interruption of moderate (load) currents. SF6 dissociates during arcing into its atomic constituents, one sulfur atom and six fluorine atoms.

  • SF6 positive DC partial discharge decomposition

    Abstract. The condition monitoring and fault diagnosis method based on decomposed component analysis (DCA) for SF 6 gas‐insulated equipment, which mainly aiming at AC SF 6 gas‐insulated equipment, has become a research hotspot. Therefore, SF 6 positive DC partial discharge (PD) decomposition experiments under four typical insulation defects were conducted in this work.
