Analysis of the Influences of the Electromagnetic Field Produced by an Electrified Railway Section

The paper presents a method of calculating the self and mutual impedances of the catenary system used in the railway electric traction in Romania followed by an analysis of the influences of the electromagnetic field produced by a section of electrified railway. The paper presents the analysis of the influences of the electromagnetic field produced by the electrified railway on the metallic objects in their vicinity. The study finds its applicability since the design phase of the electrification system. Thus, the obtained results represent information that will be validated by experimental tests in the execution phase regarding the level of electromagnetic influences on the surrounding environment of the electrified railway.

I. Introduction

Electric traction, regardless of its type, for rail, subur-ban or urban transport, through its voltage and current influences both the supply system and the neighboring installations and constructions (overhead lines and power lines, telecommunications, etc. or underground metal structures).
