Abstract
Lightning has caused lot of damages to not only human beings, but structures, power transmission and distribution systems and transportation systems. Furthermore, recent information-oriented society becomes more vulnerable to lightning than that of old days. To understand lightning, several kinds of lightning observations have been carried out and novel observation equipments using opt-electronics technology have been developed. Based on the observations and theoretical analysis, lightning protection design has been established. In this article, lightning hazards, lightning observation techniques and lightning protection design are reviewed. Problems for future studies are also demonstrated.
