(Main)High-voltage switchgear and controlgear -- Part 203: Gas-insulated metal-enclosed switchgear for rated voltages above 52 kV
High-voltage switchgear and controlgear -- Part 203: Gas-insulated metal-enclosed switchgear for rated voltages above 52 kV
Specifies requirements for gas-insulated, metal-enclosed switchgear in which the insulation is obtained, at least partly, by an insulating gas other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. For the purpose of this standard, the terms GIS and switchgear are used for gas-insulated metal-enclosed switchgear. The gas-insulated metal-enclosed switchgear covered by this standard consists of individual components intended to be directly connected together and able to operate only in this manner. This standard completes and amends, if necessary, the various relevant standards applying to the individual components constituting GIS. This first edition of EN 62271-203 cancels and replaces the third edition of EN 60517, published in 1990, and constitutes a technical revision. With the revision, significant changes from the previous edition have been made. The most important changes are deleting not used technologies, like 3-phase PD measurements, adopting the content to EN 62271-1 'Common Clauses' and harmonisation with IEEE C37.122. This standard is now more up to date to today's products on the world market. This International Standard should be read in conjunction with EN 60694, second edition, published in 1996, its Amendment 1 (2000) and its Amendment 2 (2001), to which it refers and which is applicable unless otherwise specified.

Appareillage à haute tension -- Partie 203: Appareillage sous enveloppe métallique à isolation gazeuse de tensions assignées supérieures à 52 kV
Spécifie les exigences pour l'appareillage sous enveloppe métallique à isolation gazeuse dont l'isolation est réalisée, au moins partiellement, par un gaz isolant autre que l'air à la pression atmosphérique, pour courant alternatif de tensions assignées supérieures à 52 kV, pour l'installation à l'intérieur et à l'extérieur, et pour des fréquences de service inférieures ou égales à 60 Hz. Dans le cadre de la présente norme, les termes PSEM et appareillage sont utilisés pour appareillage sous enveloppe métallique à isolation gazeuse. L'appareillage sous enveloppe métallique à isolation gazeuse auquel s'applique cette norme est constitué par des matériels individuels destinés à être directement raccordés entre eux et ne pouvant fonctionner que sous cette forme. Cette norme complète et modifie, si nécessaire, les différentes normes spécifiques applicables aux matériels individuels constitutifs de l'appareillage sous enveloppe métallique à isolation gazeuse. Cette première édition de la EN 62271-203 annule et remplace la troisième édition de la EN 60517 publiée en 1990, et constitue une révision technique. Avec cette révision, des changements significatifs ont été apportés par rapport à l'édition précédente. Les changements les plus importants sont la suppression des techniques inutilisées telles que les mesures de décharges partielles triphasées, l'adoption du contenu de la EN 62271-1 Clauses communes

Foreword
The text of document 17C/312/FDIS, future edition 1 of IEC 62271-203, prepared by SC 17C, High-
voltage switchgear and controlgear assemblies, of IEC TC 17, Switchgear and controlgear, was
submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 62271-203 on
2004-02-01.
This European Standard supersedes EN 60517:1996 + A11:1999.
Significant technical changes with respect to EN 60517:1996 are as follows: deleting not used
technologies, like 3-phase PD measurements, adopting the content of EN 62271-1, Common clauses
(under preparation), and harmonisation with IEEE C37.122. This makes the standard more up to date
to today's products on the world market.
This standard is to be read in conjunction with EN 60694:1996 + A1:2000 + A2:2001, to which it refers
and which is applicable unless otherwise specified. In order to simplify the indication of corresponding
requirements, the same numbering of clauses and subclauses is used as in EN 60694. Amendments
to these clauses and subclauses are given under the same numbering, whilst additional subclauses
are numbered from 101.
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) 2004-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-02-01
Annexes ZA and ZB have been added by CENELEC.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62271-203 has been prepared by subcommittee 17C: High-voltage
switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and
controlgear.
This first edition of IEC 62271-203 cancels and replaces the third edition of IEC 60517,
published in 1990, and constitutes a technical revision.
With the revision, significant changes from the previous edition have been made. The most
important changes are deleting not used technologies, like 3-phase PD measurements,
adopting the content to IEC 62271-1 ‘Common Clauses’ and harmonisation with IEEE C37.122.
This standard is now more up to date to today’s products on the world market.

The text of this standard is based on the following documents:
FDIS Report on voting
17C/312/FDIS 17C/316/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This International Standard should be read in conjunction with IEC 60694, second edition,
published in 1996, its Amendment 1 (2000) and its Amendment 2 (2001), to which it refers and
which is applicable unless otherwise specified. In order to simplify the indication of
corresponding requirements, the same numbering of clauses and subclauses is used as in
IEC 60694. Amendments to these clauses and subclauses are given under the same
numbering, whilst additional subclauses, are numbered from 101.
The committee has decided that the contents of this publication will remain unchanged
until 2010. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

COMMON NUMBERING OF IEC 62271 PUBLICATIONS FALLING UNDER
THE RESPONSIBILITY OF SUBCOMMITTEES SC 17A AND SC 17C
In accordance with the decision taken at the joint SC 17A/SC 17C meeting in Frankfurt, June
1998 (item 20.7 of 17A/535/RM), a common numbering system has been established for the
publications falling under the responsibility of SC 17A and SC 17C. IEC 62271 – High-voltage
switchgear and controlgear is the publication number and main title element for the common
publications.
The numbering of these publications will apply the following principle.
a) Common standards prepared by SC 17A and SC 17C will start with IEC 62271-1.
b) Standards of SC 17A will start with IEC 62271-100.
c) Standards of SC 17C will start with number IEC 62271-200.
d) Publications prepared by SC 17A and SC 17C will start with number IEC 62271-300.
The table below relates the new numbers to the old numbers. The parts numbered (xxx) will be
given a final number pending the decision to publish the revised publication as standard or
technical report.
