Evaluation of location efficency by comparing lightning faults on overhead transmission lines and Blitzortung

Abstract:
We evaluated the location efficiency and location accuracy of Blitzortung, a lightning location device introduced in Japan. We compared data from 91 transmission line lightning faults in 2019 that matched LLS with Blitzortung data. As a result, the location efficiency was 88% and the median position accuracy was 1.7 km. Moreover, of the 11 cases that were not located, the six-station-simultaneous conditions were changed to four-station-simultaneous conditions and re-calculated, after which another four cases could be located. Therefore, 84 out of 91 cases (92 %) could be located.
