摘要
推导出了在不同的零线阻抗下，各相用电设备的电压和中性点偏移电压的计算公式，讨论了零线故障对安全用电的影响，并提出了一种保护方式。
Expressions for voltage of each phase and voltage deviation of the neutral point are derived for different impedances of the neutral wire in three-phase furline system. The influence of the neutral wire frouble on power consumption is discussed and a protective measure is proposed.
