Research on the fault of neutral linein the power system

摘要

In our common low-voltage three-phase four-wire power supply system, the neutral line is often burned. Because the fault is difficult to find, so it easily causes some electrical equipments destroyed, and even causes a fire which results in enormous economic losses. Based on MATLAB simulation and simulation experiment, the impact of electrical equipments induced by the fault of neutral line is studied and the risk of fault is also verified.
