Papua New Guinea Distributed Fault Diagnosis System for Transmission Lines

Due to the technical limitations of the traditional transmission line fault location device, it is difficult to quickly and accurately locate the fault point and identify the fault type when the fault of the transmission line occurs in the complex operating environment (lightning strike, mountain fire, wind deviation, tree barrier, floating object, etc.). The distributed fault diagnosis device for transmission lines is based on fault local recording technology and traveling wave location method, which can effectively solve the problems of low positioning accuracy and difficult identification of fault types of traditional fault location devices.
The device can be connected to the lightning monitoring system of various municipal bureaus and meet the requirements of safe access. The device is mounted and operated on the transmission line, and the waveform data at the time of failure can be automatically uploaded to the central master station by wireless communication. Based on the cooperative analysis of waveforms of multiple monitoring points, the central master station can accurately locate the fault point, identify lightning strike/non-lightning strike faults, and automatically generate fault information, thus providing technical guarantee for improving line patrol efficiency and shortening fault recovery time.
