三相四线制供电方式零线阻抗对负载相电压偏移的影响

The Influence of Zero Wire Impedance in the Three phase and Four wire System

介绍了三相四线制供电方式零线阻抗对负载相电压的偏移的影响，从理论上分析其产生偏移的原因，并提出在实际应用中应注意的问题。

Usually phase voltage deviation in loading ends exists in the three phases and four wire system. In this paper, the author makes a detailed analysis of the reasons of the deviation and raises some points which are needed to be paid attention to in the application of the four wire system.
