Novel Strategy of Detecting Earth Fault Location and Its Application in Power Transmission Line

摘要：

The single-phase earth fault usually happens in power distribution line, but it is very difficult to detect most earth fault locations. The traditional methods have great difficulty in detecting earth fault, cannot quickly resume supplying power for customers and affect reliability of power supply. Tongzhou Power Supply Company of Beijing Electric used signal infusion, detection and other international advanced fault location technology to organize a large scale experiment. The results prove that the technology has a great effect on detecting earth fault and can meet the needs of real application. It introduces the technology in the experiment and test process in detail and reaches primary conclusions, which is of great importance to resolve problems in China.
