C 5 F 10 O-CO 2 mixtures are possible alternatives to SF 6 - which has a high global warming potential - as the interruption medium in gas circuit breakers. This paper experimentally studies the arcing characteristics of C 5 F 10 O-CO 2 mixture, with an experimental model with viewing windows, and measures the arc voltage, current and emission spectrum. The arc evolution process is captured with a high speed camera through an inspection window. The two-dimensional distribution of arc is obtained and analyzed by the inverse transformation of Abel. The results show that, the C 5 F 10 O-CO 2 mixture arc is more volatile than SF 6 gas, and adding C 5 F 10 O into CO 2 improves the stability of the arc, and significantly reduces the arc temperature.
