Analysis of Lightning Strike Faults in Ultra-High Voltage Transmission Lines and Research on Treatment Measures

This paper analyzes the causes of lightning faults in ultra-high voltage transmission lines of the power grid, including discharge traces and channels, grounding resistance detection, lightning resistance level simulation, and lightning resistance level calculation, in order to obtain the causes of lightning faults. Based on the analysis of lightning faults, six governance measures to avoid lightning faults are proposed, providing reference for reducing the frequency of lightning faults in ultra-high voltage transmission lines.
