language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

Foreword
This European Standard was prepared by SC 9XC, Electric supply and earthing systems for public transport
equipment and ancillary apparatus (fixed installations), of Technical Committee CENELEC TC 9X, Electric
and electronic applications for railways.
This European Standard supersedes EN 50152-2:1997 and has been prepared taking into account the
changes that have been made in the high voltage switchgear and controlgear Standards of IEC TC 17 and
in EN 50124-1/A2:2005.
This document is technically equivalent to EN 50152-2:1997 except for the normative references which
have changed and the revised classification of rated insulation voltages according to Table A.2 of
EN 50124-1/A2:2005.
The text of the draft was submitted to the unique acceptance procedure and was approved as EN 50152-2
on 2007-07-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-07-01
– latest date by which the national Standards conflicting
with the EN have to be withdrawn (dow) 2010-07-01
This Part 2 is to be used in conjunction with EN 62271-102, and/or EN 60265-1, depending from the
equipment involved.

Introduction
EN 50152 series is divided as follows:

guide.

phase current transformers.
Part 3-3: Measurement, control and protection devices for specific use in a.c. traction systems – Single-
phase voltage transformers.
EN 50152-2 has to be used in conjunction with EN 62271-102 and EN 60265-1.
Where a particular Clause of EN 62271-102 and EN 60265-1 is not mentioned in this standard, that Clause
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 62271-102 and EN 60265-1 is to be adapted accordingly.
The numbering of clauses in EN 60694, EN 62271-102 and EN 60265-1 is not used in this European
Standard. The numbering in square brackets refers to the numbering of clauses in EN 60694, EN 62271-102
and EN 60265-1.
NOTE 1 Where terms defined in EN 62271-102 and EN 60265-1 conflict with definitions of same terms as given in
IEC 60050-811:1991, or the other railway applications documents listed in the normative references, the definitions
used in EN 62271-102 and EN 60265-1 are to be used.
NOTE 2 The suffix N which appears in this Standard for rated values is not used in EN 62271-102 and EN 60265-1.
