| Abstract: | This paper introduced the basic principle of arc fault detection（AFD）. The current situation and the difficulty of AFD technology and its application were analyzed. Wave characteristic of series-arc fault and parallelarc fault were discussed respectively. The frequency spectrum analysis was proposed to improve the reliability of AFD. It is an effective means of arc AFD ,which is helpfull to the research of arc characteristics. |
