Lightning protection of overhead power distribution lines — Outage aspects, mitigation methods and future projects

Abstract

This document shows the lightning outage aspects on overhead power distribution lines (OPDLs) mainly in Japan and a designing method of the insulation level of OPDLs. Based upon detailed analysis of them the author proposed the mitigation methods, which is thought to be meet risk management of OPDLs. Moreover the author indicates the future subjects related to lightning protection of OPDLs.
