| 摘 要： | 故障的精确定位可大大提高电力系统的运行效率。利用GPS同步时钟，可以实现故障的时差定位。为此，分析了高压线路故障时差定位系统的定位原理及对传感器的要求，介绍了几种传感器，提出了一种安装方便、响应快速的电流传感器及采用电流传感器的定位系统，并在3km长的同轴电缆（模拟4．5km线路）上进行了模拟测距试验，测距误差很小，试验结果令人满意。

| Abstract: | The paper analyzes the mechanism of travelling wave based on fault location on high voltage transmission lines and the requisition for the sensor, and discusses some types of sensors. A current transformer with rapid response time is proposed, which is easy to install. A fault locator by using such a current sensor is also described. In the end, a test is made on a 3km long coaxial cable for simulating a 4.5km high voltage transmission line. The result of the test shows that the locating error is not longer than 60m, which means the locating system is satisfied. |
