要約(日本語): Lightning surge characteristics of Okushishiku test transmission line has been reported. Surge impedance of No. 30 tower of this test transmission line was reported as 120-Ohm and that of the same tower was reported to be 92.5-Ohm based on the direct method in a full-scale experiment. It was proposed that the value of surge impedance of 60-Ohm would better reproduce experimental results on the same transmission line.In this presentation, tower surge characteristics of the same tower is characterized by Numerical Electromagnetics Code (NEC-2), and is compared with the experiment. The ap-parent propagation velocity of lightning surge in the tower is also discussed.
