“…Strictly speaking, lightning current flowing in a power distribution line because of a stroke on communication tower consists of that flowing in service wire and that flowing into grounding electrode of the distribution line due to rise of ground potential of the communication equipment ; however, we ignore the influence of the rise of ground potential in this analysis, leaving it for future research.…”

“…Thus, it became clear that use of overhead ground wires (OGW), including stranded wires, upgrade of discharge capacity of lightning arresters, and other measures improve back flashover protection of high‐voltage distribution lines in winter lightning areas . It was also shown that reduction of grounding resistance in equipment exposed to direct lightning strokes (hilltop loads, wind power generators, and so on) provides efficient protection of high‐voltage distribution lines from back flashover .…”

SUMMARY Recently, with the expansion of communication network areas, the number of radio communication stations built in the neighborhood of customer houses has increased. If lightning strikes a communication radio tower, part of the lightning current flows into the distribution line and into customer houses. This may cause the failure of distribution lines or customer equipment. To protect distribution lines and customer equipment from lightning faults, it is necessary to analyze the surge phenomena in distribution lines and customer equipment and take appropriate protection measures. In this study, we examined the effect of lightning protection measures for distribution lines and customer equipment against lightning strikes to a communication tower. First, using an actual‐scale test distribution line, we measured the lightning current flowing into distribution lines and customer equipment. Second, we quantitatively examined the effect of lightning protection measures by lighting surge analysis while changing each parameter. From the experimental and analytical results, we show that the proposed protection measures can reduce the lightning current flowing into distribution lines and customer equipment.
