Abstract

Field study of lightning stroke effects, particularly the mechanisms underlying the production of line faults, is essential for designing rational lightning protection for distribution lines. The Tokyo Electric Power Company has conducted photographic research and observed voltage and current waveforms due to lightning strokes in actual distribution lines since 1996, obtaining 284 datasets, including 62 for direct hits to the lines. Combining lightning surge waveforms with photographs provides a comprehensive observation of each lightning flash and its effects. This paper experimentally evaluates observed datasets due to lightning flashes, and estimates the effect of lightning protection devices such as ground wires. These results can serve as a valuable resource to clarify lightning effects in distribution lines, and can lead to effective lightning protection practices.
