Abstract

A maintenance information system for overhead power lines is described. It was developed and put into practical use to assure a stable and reliable supply of electrical power. By using tension sensors, various kinds of meteorological sensors, and TV cameras, this system monitors snow accretion on power lines running through snowy mountainous areas. Sensor data are transmitted through optical fibers within the composite fiber-optic overhead ground wire. The central monitoring equipment performs distributed processing using several personal computers to share the tasks effectively
