  • SF6 positive DC partial discharge decomposition

    Therefore, SF 6 positive DC partial discharge (PD) decomposition experiments under four typical insulation defects were conducted in this work. The result showed that there is a significant correlation between the generation rules of the five SF 6 decomposition components (CF 4, CO 2, SO 2 F 2, SOF 2 and SO 2) and the types of defects.

  • Study of decomposition of sulphur hexafluoride by gas

    Abstract When electrical discharges occur in sulphur hexafluoride gas (SF 6) lower fluorides are produced within the discharge, and they in turn react readily with impurities, insulators and the electrodes. The final stable compounds formed include sulphur oxyfluorides and sulphur oxides.
