Abstract

The article represents results of a physical simulation of incomplete upward leader discharges induced on air transmission lines’ elements, using charged artificial thunderstorm cells of negative polarity. The influence of such discharges on closely located model sensors (both of rod and elongated types) of digital monitoring systems, as well as on the models of receiver-transmission systems of local data collection (antennas), was determined. Effect of heterogeneity of electromagnetic field caused by incomplete upward discharges on frequency specter of signals generated on sensors and antennas was estimated. Wavelet analysis was carried out to determine the basic frequency diapasons of such signals. Based on experimental data obtained, suppositions about the extent of influence of nearby incomplete leader discharges on the functioning of currently used systems of transmission lines’ monitoring were made.

Highlights

Remote monitoring systems are increasingly being introduced into the management of transmission lines and become an important element of digital power industry [1,2,3,4,5,6,7,8,9,10,11]
It was observed that the functionality of the artificial intelligence elements used in such systems may be compromised under the influence of lightning and atmospheric electricity [3,11,12]
It is not entirely clear how the discharge phenomena forming on both rod and elongated ground objects under the influence of thunderclouds and lightning and the electromagnetic radiation they create will affect functioning of such elements [13,14]

Summary

Introduction

Remote monitoring systems are increasingly being introduced into the management of transmission lines and become an important element of digital power industry [1,2,3,4,5,6,7,8,9,10,11] During their exploitation, it was observed that the functionality of the artificial intelligence elements used in such systems (i.e., all devices that contain electromagnetic parts, e.g., sensors; analog–digital converters for processing of recorded signals; antennas, etc.) may be compromised under the influence of lightning and atmospheric electricity [3,11,12]. This work is a continuation of [15], where the characteristics of streamer discharges that did not pass into the ascending leader were considered
