抄録

Nearby trees and buildings affect frequency of direct lightning strokes to distribution lines because the lines can be located lower than nearby structures. It is necessary to grasp lightning performance in distribution lines based on observation data. Lightning phenomena on actual distribution lines have been continuously observed for the last 10 years to rationalize lightning protection designs. The observation has been carried out with still cameras and monitoring sensors of lightning surges. The observation has clarified the frequency of direct lightning strokes to distribution lines, and the ratio of flashover probability. Those results can be useful to calculate the lightning faults rate of distribution lines.
