本文提出了一种利用磁调制原理检测直流系统接地故障的新方法。该方法不仅可以通过在直流母线上加一个电阻来确定单个漏电回路，还可以同时确定正母线和负母线绝缘故障的特殊情况。最后在论文中展示了良好的结果。该检测装置选择环路性能良好，抗干扰能力强，经实验未发现对直流系统产生任何影响。
A novel method of detecting an earth fault on a DC system is by the principle of magnetic modulation is proposed in the paper. The method can determine not only individual leakage loop but also the special case of both positive bus wire and negative bus wire insulation fault simultaneously by putting a resistance into the DC bus. Finally, the good results are shown in the paper. The performance of the detecting apparatus is good in the selection loop and strong in anti-interference, as well as it not showing any effect on the DC system through the experiment.
