Railway applications - Electromagnetic compatibility -- Part 5: Emission and immunity of fixed power supply installations and apparatus
This European Standard applies to emission and immunity aspects of EMC for electrical and electronic
apparatus and systems intended for use in railway fixed installations for power supply. This includes
the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items
such as switching stations, power autotransformers, booster transformers, substation power
switchgear and power switchgear to other longitudinal and local supplies.
Filters operating at railway system voltage (for example, for harmonic suppression or power factor
correction) are not included in this standard since each site has special requirements. Filters would
normally have separate enclosures with separate rules for access. If electromagnetic limits are
required, these will appear in the specification for the equipment.
The limits in this standard do not apply to intentional communication signals.
The frequency range considered is from DC to 400 GHz. No measurements need to be performed at
frequencies where no requirement is specified.
Emission and immunity limits are given for items of apparatus which are situated:
a) within the boundary of a substation which delivers electric power to a railway;
b) beside the track for the purpose of controlling or regulating the railway power supply, including
power factor correction;
c) along the track for the purpose of supplying electrical power to the railway other than by means of
the conductors used for contact current collection, and associated return conductors. Included are
high voltage feeder systems within the boundary of the railway which supply substations at which
the voltage is reduced to the railway system voltage;
d) beside the track for controlling or regulating electric power supplies to ancillary railway uses. This
category includes power supplies to marshalling yards, maintenance depots and stations;
e) various other non-traction power supplies from railway sources which are shared with railway
traction.
The immunity levels given in this standard apply for
- vital equipment such as protection devices;
- equipment having connections to the traction power conductors;
- apparatus inside the 3 m zone;
- ports of apparatus inside the 10 m zone with connection inside the 3 m zone;
- ports of apparatus inside the 10 m zone with cable length > 30 m.
Apparatus and systems which are in an environment which can be described as residential,
commercial or light industry, even when placed within the physical boundary of the railway substation,
shall comply with the relevant generic European EMC standard.
Excluded from the immunity requirements of this standard is power supply apparatus which is
intrinsically immune to the tests defined in Tables 1 to 6 of this standard.
NOTE An example is an 18 MVA 230 kV to 25 kV power supply transformer.
These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.
This part of the standard covers requirements for both apparatus and fixed installations. The sections
for fixed installations are not relevant for CE marking.

Applications ferroviaires - Compatibilité électromagnétique -- Partie 5: Emission et immunité des installations fixes d'alimentation de puissance et des équipements associés
La présente Norme Européenne s’applique aux aspects d’émission et d’immunité de CEM pour les appareils et les systèmes électriques et électroniques destinés à être utilisés dans les installations fixes associées à l’alimentation. Cela concerne l’alimentation des appareils, les appareils eux-mêmes avec leurs circuits de commande de protection, les composants au bord des voies tels que les stations de sectionnement, les autotransformateurs, les transformateurs suceurs, les appareillages de coupure de sous-station et les appareillages de coupure d’autres alimentations longitudinales et locales.
Les filtres qui fonctionnent à la tension du système ferroviaire (par exemple, pour la suppression d’harmoniques ou la correction de facteur de puissance) ne sont pas inclus dans la présente Norme dans la mesure où chaque site répond à des exigences spéciales. Normalement, les filtres sont dans des enceintes séparées avec des règles d’accès particulières. Si des limites électromagnétiques sont nécessaires, elles apparaîtront dans la spécification pour l’équipement.
Les limites de la présente Norme ne s’appliquent pas aux signaux de communication intentionnels.
La plage de fréquences concernée va du courant continu à 400 GHz. Aucune mesure n’est nécessaire aux fréquences pour lesquelles aucune exigence n’est spécifiée.
Les limites d’émission et d’immunité sont données pour les composants des appareils qui sont situés:
a) dans les limites de la sous-station qui alimente le réseau de traction en électricité;
b) près des voies pour contrôler et réguler l’alimentation électrique du réseau de traction, y compris la correction de facteur de puissance;
c) le long de la voie pour fournir de l’énergie électrique au système ferroviaire par d’autres moyens que les conducteurs utilisés pour le captage du courant de contact et les conducteurs de retour associés. Ceci englobe les systèmes d’alimentation à haute tension dans les limites du système ferroviaire qui alimentent les sous-stations dans lesquelles la tension est ramenée à la valeur de la tension du système ferroviaire;
d) près des voies pour contrôler et réguler les alimentations électriques utilisées à différents usages ferroviaires auxiliaires. Cette catégorie englobe les alimentations des installations de triage, des dépôts de maintenance et des gares;
e) différentes alimentations qui ne concernent pas la traction alimentées par une des sources ferroviaires qui sont partagées avec la traction ferroviaire.
Les niveaux d’immunité donnés dans la présente Norme s'appliquent aux
- équipements vitaux tels que les dispositifs de protection;
- équipements dotés de raccordements vers les conducteurs de puissance de traction;
- appareils situés dans la zone de 3 m;
- accès des appareils situés dans la zone de 10 m avec connexion dans la zone de 3 m;
- accès des appareils situés dans la zone de 10 m avec longueur de câble > 30 m.
Les appareils et les systèmes qui sont dans un environnement qui peut être décrit comme résidentiel, commercial ou d’industrie légère, même s’ils sont situés dans les limites physiques de la sous-station ferroviaire, doivent être conformes à la norme générique européenne CEM applicable.
Les appareils d’alimentation qui ont une immunité intrinsèque aux essais définis aux Tableaux 1 à 6 de la présente Norme sont exclus des exigences relatives à l’immunité de la présente Norme.
NOTE Un transformateur 18 MVA 230 kV / 25 kV en est un exemple.
Ces dispositions spécifiques doivent être utilisées avec les dispositions générales données dans l'EN 50121 1.
La présente Partie de la Norme couvre à la fois des exigences pour les appareils et les installations fixes. Les sections pour les installations fixes ne sont pas applicables au marquage CE.

Introduction
The requirements of this standard have been specified so as to ensure a level of electromagnetic
emission which will cause minimal disturbance to other equipment. The levels, however, do not cover
the following cases:
a) which may occur with an extremely low probability of occurrence in any location;
b) where highly susceptible apparatus will be used in close proximity of the equipment covered by
this standard, in which case further measures may have to be taken.
The emission limits given are on the basis that the equipment of the product family range is installed in
railway substation areas.

4 Performance criteria
The variety and diversity of the apparatus within the scope of this document make it difficult to define
precise criteria for the evaluation of the immunity test results. Three general levels of performance are
therefore used, as defined in EN 50121-1.
5 Emission tests and limits
5.1 Emission from the substation to the outside world
Limit values for this emission, over the frequency range 150 kHz to 1 GHz are given in EN 50121-2.
Guidance values are given in EN 50121-2 for emission of d.c. and power frequency magnetic fields.
Conductors (overhead or underground) between the substation and the railway are part of the railway
installation, but because of their wide variety of positions and ampere loadings, limit values cannot be
set for the magnetic fields which they produce.
No limits are set for emissions into the active space of the underground railway due to the complexities
of obtaining measurements in the confined space and the lack of a precise method of relating the
measured values to the degree of disturbance which other apparatus would suffer.
No measurements are necessary for total underground railway systems with no surface operation.
