Abstract

Damage of home appliances, such as personal computers and fax machines has a great influence on highly sophisticated information society. Surge protective devices (SPD) are expected to be prevalent because installation of the SPD at a switchboard is recommended in the regulation on indoor wires revised in 2005. In this study, experiments were conducted with a full-scale distribution system and interior wiring in order to clarify lightning response to surges intruding from service wires. The results confirmed that SPD at a switchboard with common grounding wire is effective for protecting home appliances. But in some cases, surge current could propagate into communication lines when the ground wires of SPDs at a switchboard and of a communication appliance are connected each other.
