| 摘 要： | 在倒置电桥法测量电力电缆故障的基础上，提出了一种消除接地电流的新方法。在应用倒置电桥法测量之前，接入一套由电阻和直流电源组成的接地电流消除电路，通过调节可调电阻器消除其接地电流。分析了该方法的基本电路原理，给出了推导过程，并通过模拟实验验证了该测量方法的有效性。 |

| Abstract: | This paper presents a new measure to eliminate the ground current for fault location of power cable and analyses the basic principle of inversion bridge method.Before using the inversion bridge method for fault location,switch-on a circuit combined with resistances and direct-current source,the ground current can be completely eliminated by adjusting the resistance value.The paper analyses the eliminating measure circuit principle,sets out the deducing process,and sets up a model experiment to test the vali... |
