Retracted: Fault Identification Technology for Overhead Transmission Lines

With large cross-domains and long distances, overhead transmission lines are easily affected by various natural disasters such as lightning strikes, external damage and bird trouble in complex terrains, resulting in line tripping fault. In this paper, fault characteristics of overhead transmission lines are studied and analyzed, and it is found that different fault types of overhead transmission lines have different characteristics in time, reclose and fault recording. A line tripping fault was analyzed, and it verified the effectiveness of the fault identification technology for overhead transmission lines. Based on the study on fault characteristics of overhead transmission lines, operation and maintenance personnel can quickly find the cause of fault tripping by using fault feature identification technology and it is good for improving the reliability of transmission line operation through targeted management and technical means.
