要約(英語): In order to protect electrical equipment from lightning, it is important to learn about the actual situation of electrical equipment damages due to lightning. We are continuously investigating lightning damage from 2011, and we conducted lightning damage field surveys 17 times (151 locations) in the Tohoku region. As a result of the investigation, we confirmed that 753 electrical equipment were damaged due to lightning in houses and enterprise places. The number of lightning damages on low-voltage equipment is more than high-voltage equipment, 668 low-voltage equipment such as telephones, televisions, water heaters, personal computers and lighting equipment were damaged due to lightning, accounting for about 85% of the total. In this paper, we described the actual situation and cases of lightning damage to low-voltage equipment, and also described the comparison with the past results of lightning damage investigations.
