This paper mentioned a new method for the monitor system of arcing fault based on the characterization information of sound arc,arc and short-circuit current.The process of arcing fault protection was separated in two stages.First,arcing sound appeared before it burning,the system sent out early warning at once.If the fault was not precluded in time,then arcing light and short-circuit current would occur,meanwhile the system would send out warning.Second,the experimental platform was created,and its average amplitude frequency spectrum was calculated.The wave peak of arcing light and short-circuit current were detected,and appropriate threshold values were established by experiment.Experiment proves that the system can do double protection to arcing fault.
