要約(英語): Lightning protection design of substations and underground transmission lines adopts deterministic method. In this deterministic, necessity of lightning protection measures is determined by lightning overvoltage calculated by lightning surge analysis. In usual, it is necessary to calculate overvoltage against each power apparatus. However, lightning overvoltage in underground transmission lines is able to categorize by some cases. Therefore, lightning protection design of underground transmission lines can be simplified by using Voltage -length curves.
