Abstract

This paper deals with a proper installation methods of SPDs for information-oriented and computerized equipments. Since the information and computerized equipments have AC power lines and communication lines, the potential difference by lightning surge occurs between grounding points of the AC power lines and subscriber protectors, and it causes the flashover and damage. So, we have investigated the effect of the installation methods of surge protectors on the control of overvoltages, using a real-sized test circuit with a customer's facility. As a consequence, it was confirmed that the protection methods by installation of SPDs on the neighbor branch circuit was effective.
