Performance Enhancement and Key Technologies of Distributed Fault Diagnosis System for Overhead Power Lines

The distributed line fault diagnostic device is suitable for aerial transmission lines from 35kV to 1000kV and plays a significant role in the maintenance of the lines after fault occurrences. Although this system has been applied to some extent in the power production field, it still faces issues such as poor power supply stability, difficulty in capturing micro-small amplitude abnormal discharge traveling waves, loss of large original fault waveform files due to their size, and the inability to deploy devices in areas without 4G networks. These issues severely affect the stable operation of the distributed line fault diagnostic device. This paper proposes reasonable and feasible solutions to the aforementioned problems and describes the specific technical routes for implementing these solutions. The resolution of these issues has effectively improved the overall performance of the device during actual operation.
