A Protection Technique of Information and Communication Facilities from Lightning Surges

초록

In this work, in order to develop the reliable ways to protect information and communication facilities from lightning surges, the reliability and performance of surge protective devices were experimentally investigated in actual-sized test circuit. The operation behaviors of surge protective devices against lightning surges from the AC power lines and telecommunication lines and the coordinated effects of SPD installation methods were in detail evaluated. As a consequence, it was confirmed that the bypass arrester with the common grounding system is very effective to protect electronic equipments from lightning surges.
