SF6 decomposition pipes GE

2021-2-8The study of sulfur hexafluoride (SF6) discharge is vital for its application in gas-insulated equipment. Direct current partial discharge (PD) may cause SF6 decomposition, and the decomposed products of SF6, such as F atoms, play a dominant role in the breakdown of insulation systems.

    SF6 is usually diluted with these two gases in order to reduce the release of SF6 and the associated environmental impact. However, the dielectric strength of a mixture of SF6 with Air or with CF4 is always lesser leaser than that of pure SF6. SF6 mixture with air/ CF4 has greater arcing time and the interruption derating occurs.
