Application of lightning optical path monitoring system on 500kV transmission lines in mountain area

In order to obtain optical path photographs of lightning strike with a higher resolution, providing the necessary technical means for the accurate identification of 500kV transmission line lightning fault in mountain area, we developed an embedded, low-power remote online Lightning Optical Path Monitoring System based on 3G communication technology. Then, a case containing a lightning which struck the transmission line was analyzed in this paper combined with the results of the Lightning Optical Path Monitoring System, State Grid Lightning Location System and the Transmission Line Distributed Fault Diagnosis System.
