The forms and the V-I characteristics of vacuum arc have great influence in the vacuum circuit breakers’ protection and control of power system. An experimental set-up was thus designed for vacuum switching arc measurement of V-I characteristics was used and an image collection system was designed to collect the images of vacuum arc used high-speed camera CMOS with the experimental setup, the V-I characteristics and forms of vacuum arc was researched, the curve of V-I was drawn and the images was analyzed. All these provide experimental basis for the analysis on basic physical theory of vacuum switching arc.
