要約(英語): Due to the progress of information-oriented societies all over the world, telecommunication cables are often installed on concrete poles along with power distribution lines. When a lightning stroke hits a concrete pole equipped with an overhead ground wire and a telecommunication cable, the lightning current is split into the three paths: the concrete pole, the overhead ground wire, and the telecommunication cable. It is easily estimated that the existence of the telecommunication cable reduces the current through the concrete pole, and thus, reduces the voltages across the insulators which support the phase wires. However, its quantitative study has not yet been carried out. In this paper, we clarified the effect of the telecommunication cable on reducing the voltages across the phase-wire insulators from the both sides of an actual-scale distribution line test and EMTP (Electro-Magnetic Transients Program) analysis.
