Abstract As an excellent insulating medium, sulfur hexafluoride (SF₆) is widely used in gas- insulated apparatus. Previous studies and actual operation experiences have shown that the insulation condition of gas-insulated apparatus can be assessed via decomposition by-products of SF₆. Therefore, the analysis on gaseous by-products is one of the most effective ways in monitoring the insulation condition of gas-insulated apparatus. In this paper, by virtue of the gas chromatograph-mass spectrometer system, the qualitative as well as quantitative results of SF₆ decomposition by-products are presented in 50Hz AC point-plane corona discharge. Meanwhile, the influence factors on the formation of decomposition by-products are discussed, such as applied voltage, duration of discharge, gas pressure and distance between point and plane as so on.

Key words： SF6 corona discharge decomposition by-products of SF6 gas chromatography-mass spectrometry
