摘要

本文报道了提供不平衡非线性负载的三相四线制系统的初步研究结果。本文描述了中性点路径阻抗对电压和电流畸变的影响。研究发现，非线性负载不平衡会引起过电压和非零序三次谐波电流的注入，引起线中性点电压的显著差异，使线间电压受到轻微的三次谐波污染。

The effect of neutral path impedance on voltage and current distortion. Part II. Imbalanced three-phase systems

This paper reports the results of a preliminary study of three-phase four-wire systems that supply unbalanced nonlinear loads. The work describes the effect of neutral path impedance on voltage and current distortion. It was found that nonlinear load unbalance may cause over voltages and injection of nonzero-sequence treble harmonic currents that may cause significant differences among the line-to-neutral voltages and mildly taint the line-to-line voltages with treble harmonics.
