The Protection Effect of Lightning Surge for electronic Equipments According to Installation of Surge Protective Device and Earth Leakage Breaker

서지보호소자와 누전차단기 설치에 따른 기기의 뇌보호 효과

Lightning surge damages of low voltage equipments in building are increasing due to increase in electrical and communication networks in the information-oriented society. And electronic equipments contained electrical circuits with semiconductor are very weak against lightning surge. The surge protective devices for electronic circuit in electronic equipments and AC power lines are becoming more widely. To achieve effective method of surge protection, there are needs for correlation between lightning surge protective effect of electronic equipment and installation method of surge protective device. This paper describes as a result of experiments for correlation between lightning surge protective effect and installation of surge protective device and Earth Leakage Breaker.
