Distributed monitoring system for overhead lines insulations and substations based on wireless capacitive sensors

Abstract

In this paper proposed three modifications to the monitoring system of the overhead lines, insulation state and substations based on sensors installed on supports and insulators. The sensors operate on the principle of capacitive coupling with an insulating structure. Differences between the system modifications in the information present options: light indication for control when bypassing lines and substations and changing graphics on the computer (smartphone) screen when receiving data in real time from sensors using cellular communication. The principle of operation and functional diagrams of the system with results of tests and experiments with manufactured product samples in laboratory and field conditions are presented.
