Analysis on Distribution Characteristic and Fire Risk of Neutral-line Opening Fault

This article, which concentrated on neutral-line opening fault, simulated diversification of voltage and current according to variety of load factors by means of matlab/simulink software, as a result, the relationship between voltage & current and load factors was acquired. Based on simulated results, the possible results which may be led to by the fault was analyzed, and the distribution characteristic and fire risk of neutral-line opening fault was summarized, all of these provided the important references for exploring the reasons of electrical fires.
