Research on Adaptive Power Transmission Line Fault Inspection

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Power transmission line is one of the most important infrastructures of power system, and its safety monitoring is of great significance. The conventional way of fault monitoring of power transmission lines by only setting threshold value on single temperature data of strain clamp turned out to multiple misjudgements and delayed
