Railway applications - Fixed installations - Particular requirements for a.c. switchgear - Part 3-2: Measurement, control and protection devices for specific use in a.c. traction systems - Current transformers
This EN 50152-3-2 is applicable to new current transformers which are
for indoor or outdoor fixed installations in tractions systems, and
operated with an a.c. line voltage and frequency as specified in EN 50163.
NOTE 1 EN 50163 specifies the a.c. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz.
As rails of a.c. traction systems are connected to earth and included in the return current path all phase to earth voltages will be within the tolerances as specified in EN 50163. Nevertheless phase to phase voltages may be higher e.g. in autotransformer systems.
Current transformers are mainly used with
measurement instruments,
protective devices.
This EN 50152-3-2 shall also be applied to current transformers other than inductive types as far as reasonably possible. Requirements of this EN 50152-3-2 prevail.
NOTE 2 Combined current and voltage transformers are typically not used in fixed installations.
Bahnanwendungen - Ortsfeste Anlagen - Besondere Anforderungen an Wechselstrom-Schalteinrichtungen - Teil 3-2: Meß-, Steuerungs- und Schutzeinrichtungen für Wechselstrom-Bahnanlagen - Einphasen-Stromwandler
EN 50152-3-2 gilt für neue Stromwandler, die für
- für die Verwendung in ortsfesten Innenraum- oder Freiluftanlagen in Bahnenergieversorgungssystemen vorgesehen sind und
- mit einer Fahrleitungswechselspannung und -frequenz entsprechend EN 50163 betrieben werden.
ANMERKUNG 1 EN 50163 benennt für Bahnen die Wechselspannungssysteme 15 kV 16,7 Hz und 25 kV 50 Hz.
ANMERKUNG 2 Da bei Wechselspannungsbahnen die Gleise üblicherweise mit dem Erdpotential verbunden und Teil des Rückstromkreises sind, unterliegen alle Außenleiter-Erde-Spannungen der in EN 50163 festgelegten Grenzwerte. Dennoch sind die Spannungen zwischen den Leitern manchmal höher, z. B. in Autotransformator-Systemen.
Stromwandler werden hauptsächlich verwendet mit:
- Messgeräten,
- Schutzeinrichtungen.
EN 50152-3-2 gilt auch für Stromwandler mit vom induktiven Messverfahren abweichender Bauart, soweit dies sinnvoll möglich ist. Die Anforderungen dieser EN 50152-3-2 haben Vorrang.
ANMERKUNG 3 Kombinierte Strom- und Spannungswandler werden üblicherweise nicht in ortsfesten Anlagen von Bahnnetzen verwendet.
Applications ferroviaires - Installations fixes - Exigences particulières pour appareillage à courant alternatif - Partie 3-2: Dispositifs de mesure, de commande et de protection pour usage spécifique dans les systèmes de traction à courant alternatif - Transformateurs de courant monophasés
La présente norme EN 50152-3-2 s’applique aux nouveaux transformateurs de courant qui sont :
- destinés aux installations fixes intérieures ou extérieures dans les systèmes de traction, et
- exploités à la tension et à la fréquence d’une ligne à courant alternatif, comme spécifié dans l'EN 50163.
NOTE 1 L'EN 50163 spécifie les réseaux de traction à courant alternatif 15 kV 16,7 Hz et 25 kV 50 Hz.
NOTE 2 Dans la mesure où les rails des systèmes de traction à courant alternatif sont généralement reliés à la terre et inclus dans le chemin du courant de retour, toutes les tensions phase-terre sont soumises aux limites indiquées dans l'EN 50163. Néanmoins, les tensions entre conducteurs sont parfois plus élevées, dans les systèmes d'autotransformateurs, par exemple.
Les transformateurs de courant sont principalement utilisés avec :
- des appareils de mesure,
- des dispositifs de protection.
La présente norme EN 50152-3-2 s'applique également à des transformateurs de courant autres que ceux de type inductif, autant qu'il est raisonnablement possible. Les exigences de la présente norme EN 50152-3-2 sont prioritaires.
NOTE 3 Les transformateurs de courant et de tension combinés ne sont généralement pas utilisés dans les installations fixes des systèmes de traction.
Železniške naprave - Stabilne naprave električne vleke - Posebne zahteve za stikalne naprave za izmenični tok - 3-2. del: Merilne, krmilne in zaščitne naprave za izključno uporabo v izmeničnih vlečnih sistemih - Tokovni transformatorji
Ta standard EN 50152-3-2 se uporablja za nove tokovne transformatorje, ki se
uporabljajo za notranje ali zunanje nameščene naprave v vlečnih sistemih in
uporabljajo z izmenično napetostjo in frekvenco, kot je navedeno v standardu EN 50163.
OPOMBA 1: Standard EN 50163 določa vlečne sisteme z izmenično napetostjo 15 kV pri 16,7 Hz in 25 kV pri 50 Hz.
Ker so tiri vlečnih sistemov z izmeničnim tokom ozemljeni in vključeni v pot povratnega toka, bodo vsi vodniki do ozemljitve v mejah toka, ki so določene v standardu EN 50163. Kljub temu so lahko napetosti med vodniki višje kot na primer v sistemih z avtotransformatorji.
Tokovni transformatorji se uporabljajo predvsem z
merilnimi instrumenti,
zaščitnimi napravami.
Ta standard EN 50152-3-2 se uporablja tudi za tokovne transformatorje, ki niso induktivni, v smiselno mogočem obsegu. Prednost imajo zahteve tega standarda EN 50152-3-2.
OPOMBA 2: Kombinacije tokovnih in napetostnih transformatorjev se običajno ne uporabljajo v stabilnih napravah električne vleke.

European foreword
This document (EN 50152-3-2:2016) has been prepared by SC 9XC “Electric supply and earthing systems
for public transport equipment and ancillary apparatus (Fixed installations)” of CLC/TC 9X “Electrical and
electronic applications for railways”.
The following dates are fixed:
• latest date by which the existence of (doa) 2016-10-25
this document has to be announced
at national level
• latest date by which this document has to be (dop) 2017-04-25
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2019-04-25
conflicting with this document have to
be withdrawn
This document supersedes EN 50152-3-2:2001.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
This standard was revised to reflect the latest versions of standards referenced and to remove text already
included in the EN 61869 Series. The structure of the document was adapted to that of EN 50152-1 and
EN 50152-2. Ratings have been added to provide designations in line with other railway standards e.g.
EN 50124. Tests requirements have been detailed to meet operating conditions of railway applications.
Partial discharge voltages have been specified in Table 2.
This standard has to be read in conjunction with EN 61869-1:2009 and EN 61869-2:2012.
Where a particular clause/subclause of EN 61869-2 is not mentioned in this standard, that clause/subclause
applies as far as reasonable. Where requirements relate exclusively to three-phase systems or to voltages
outside those in use in traction systems, they are not applicable. Where this standard states “addition” or
“replacement”, the relevant text of EN 61869-2 is to be adapted accordingly.
The numbering of clauses in EN 61869 Series is similar to that in the EN 50152 Series.
Where terms defined in EN 61869-1 and EN 61869-2 conflict with definitions of the same terms as given in
IEC 60050-811:1991 or of the other railway applications documents listed in the normative references, the
definitions in EN 61869-1 and EN 61869-2 are to be used.
NOTE The suffix N which appears in this standard for rated values is not present in EN 61869–1 and EN 61869–2.
References in subclauses of EN 61869-1 and EN 61869-2 have to be replaced by references to applicable
subclauses in this standard as far as reasonably possible.
