Development of Monitor System for Lightning Observation

Abstract

There have been many lightning accidents in power system operation, but the problems have not been solved in detail. Therefore, for safety and economical power supply, it is necessary to inquire into the cause of thunderstorm thoroughly in terms of the synthetic elements of lightning phenomena. As these solution, the following studies have been made public so far. (1) The frequency distribution map of the lightning discharges in Japan. (2) Lightning channel reconstruction by thunder analysis. (3) Observation of lightning locating system. And so, this paper describes a monitor system for lightning observation by computer. This observation system is designed for measuring the lightning intensity automatically. And this monitor system is able to display the state of lightning flash counters, the parameters of lightning electric field wave while observing lightning intensity. Moreover, the parameters, proper characteristics, is obtained from lightning electric field wave and the frequency characteristic by using program of computer.
