Railway applications - Rolling stock - Testing for electromagnetic compatibility with track circuits

This document defines the measurement and evaluation methods of rolling stock interference current emissions to demonstrate compatibility with track circuits. This includes rolling stock with or without traction equipment. The established limits for compatibility are defined in ERA/ERTMS/033281, PD CLC/TS 50238 2 or NNTRs as current flowing between the vehicle and the electric traction power supply system that can disturb the track circuit receiver, as part of the track circuit system. Additionally, the referred documents can define a minimum rolling stock impedance in order to guarantee compatibility between the electric traction power supply system and track circuits. This document is relevant to the interference current limits defined in the ‘frequency management’ for track circuits as defined in ERA/ERTMS/033281. It is also applicable to the demonstration of compatibility with all other types of track circuits which have established compatibility according to EN 50617 1. Finally, the methodology defined in this document can also be applied to other track circuit types, including those for which the only requirements are defined in National Notified Technical Rules. NOTE Interface parameters between rolling stock and track circuits other than interference currents and impedance are out of the scope of this document.

Bahnanwendungen - Fahrzeuge - Prüfung der elektromagnetischen Verträglichkeit mit Gleisstromkreisen

Applications ferroviaires - Matériel roulant - Essais pour la compatibilité électromagnétique avec les circuits de voie

Le présent document définit les méthodes de mesure et d'évaluation des courants perturbateurs générés par le matériel roulant dans le but de démontrer leur compatibilité avec les circuits de voie. Il couvre le matériel roulant avec ou sans équipement de traction. Les limites fixées pour la compatibilité sont définies dans le document ERA/ERTMS/033281, dans le document premier CLC/TS 50238 2 ou dans les règles techniques nationales notifiées (RTNN). Ces limites concernent les courants, qui circulent entre le véhicule et le réseau d'alimentation électrique de traction et qui peuvent perturber le récepteur du circuit de voie. Par ailleurs, les documents cités peuvent définir une impédance minimale pour le matériel roulant afin de garantir la compatibilité entre le réseau d'alimentation électrique de traction et les circuits de voie. Le présent document traite des limites de courant perturbateur établies dans le cadre de la « gestion des fréquences » pour les circuits de voie, définie dans le document ERA/ERTMS/033281. Il s'applique également à la démonstration de compatibilité avec tous les types de circuits de voie, dont la compatibilité a été démontrée conformément à l'EN 50617 1. Enfin, la méthodologie décrite dans le présent document peut également être mise en oeuvre pour d'autres types de circuits de voie, y compris ceux dont les exigences sont uniquement définies dans les RTNN. NOTE Les paramètres d'interface entre le matériel roulant et les autres circuits de voie, autres que les courants perturbateurs et l'impédance, ne relèvent pas du domaine d'application du présent document.
