Abstract: Background and significance of studying fault arc of low—voltage distribution circuit are illustrated; and production conditions, classification and features of fault arc in circuit are analyzed in this paper.A mathematical model for single—phase arc fault of low-voltage distribution circuit is established by choosing an arc mathematical model suitable for low-voltage distribution system. W ith the simulation experiment analysis on limitation of overcurrent protection of breaker in case of arc sh0rt-circuit fault of the circuit, the necessity of using arc fault breaker is illustrated,and the application prospect of arc fault breaker is proposed.
