Measurement of lightning overvoltages on low-voltage power distribution lines

摘要

Recently, the use of many kinds of electronic appliances has grown in our daily lives, and many instances of trouble due to on low-voltage lightning electromagnetic effects have been reported. Few data of lightning surges on low-voltage power distribution lines have been reported, however. This paper shows the observation results obtained from measurements of lightning overvoltages power distribution lines at a small office building. The data of lightning overvoltages were compared with these obtained from lightning location systems and the propagation characteristics were considered.
