Abstract:By use of specially designed fault simulator for 110kV gas insulated switchgear (GIS), the production regularity of SF6 decomposition products, mostly SO2 and SOF2, and the effects of partial discharge strength, discharge forms, humidity of SF6 and absorbents on the content of SF6 decomposition products are researched. The availability of SF6 decomposition products in fault diagnosis of GIS equipments and the issues to be paid attention to are discussed preliminarily.
Keywords:gas insulated switchgear (GIS)  gas- decomposition products  fault pattern recognition  sulphur hexafluoride
