Abstract

This article discusses issues regarding electromagnetic interference generated unintentionally by transport telematics systems and electronic security systems (ESS) located within a railway area. These systems should operate correctly, since they ensure the safety of both vehicles and passengers. The electronic devices they use are exposed to electromagnetic interference that may lead to incorrect ESS functioning. In order to determine the impact of electromagnetic interference on ESS, the authors measured unintentional low-frequency electromagnetic field generated by MV—15 and 30 kV—power lines. This enabled determining the areas with maximum values of electromagnetic interference. The next stage of the research was to develop an ESS operating process model that takes into account the impact of unintentionally generated electromagnetic interference on the operating process. Introducing the electromagnetic interference impact coefficient enables a rational selection of solutions aimed at protecting against electromagnetic interference through the application of technical and organizational measures.

Highlights

Transport telematics systems and electronic security systems (ESS) located in a metal container on a railway route are considered to be the “State’s critical infrastructure items” [1,2,3]
In order to investigate the impact of medium-voltage lines on the electromagnetic environment inside and outside the container with installed transport telematics systems, the authors measured the distribution of electromagnetic field components under three power lines supplying technical facilities, i.e., a 30 kV line and two different 15 kV lines
The issue of operating transport telematics and electronic security systems located within railway areas is extremely important

Summary

Introduction

Transport telematics systems and electronic security systems (ESS) located in a metal container on a railway route are considered to be the “State’s critical infrastructure items” [1,2,3]. The authors present the results of tests involving the electromagnetic environment surrounding medium-voltage lines supplying a container security system This was used as a base to conclude that it was justified to apply solutions resulting in mitigated low-frequency electromagnetic field impact on the systems in question. In order to investigate the impact of medium-voltage lines on the electromagnetic environment inside and outside the container with installed transport telematics systems, the authors measured the distribution of electromagnetic field components under three power lines supplying technical facilities, i.e., a 30 kV line and two different 15 kV lines. The changes in the electric field strength E along the phase conductors of container-supplying MV power lines were analyzed The introduction of the ΓZB1 and ΓZB2 coefficients of electromagnetic interference in terms of impact on the ESS enables to rationally select solutions aimed at protecting against electromagnetic interference
