Wire Torsion Measurement for the Tasks of Monitoring of the Mechanical State of Overhead Power Transmission Line

摘要

A system of overhead power transmission line monitoring was developed to assess the effect of mechanical loads in a wire/ground wire on its torsion angle. The system allows measuring the torsion angle of the wire, helps to prevent possible overhead power transmission line damage by tracking the tension force, as well as conductor and pendant fitting defects. It includes a control device, a data station, and a dispatch software package. Controllers are installed directly on the wire/ground wire of the overhead power transmission line. The rotation and elevation angles and wire temperature are measured. Input data are processed in the data station with specialized software. The developed system for monitoring the state of overhead power transmission lines, which takes into account the wire rotation, will reduce the costs associated with their maintenance and repair.
