摘要
单相接地故障是造成城市路灯设施漏电隐患的主要原因。通过研究剩余电流保护器(RCD)的工作原理,找到了利用钳表快速地测量回路中剩余电流的方法,从现场作业的角度出发,提高人工排查漏电隐患的效率。
Single-phase ground fault is the main cause of potential current leakage hazard of urban street lamp facilities. By observing the working principle of residual current device(RCD), we found a method to measure the residual current in the circuit quickly with a clamp meter. From the point of view of field operation, we can improve the efficiency of manual leakage detection.
