High-voltage switchgear and controlgear - Part 103: Switches for rated voltages above 1 kV up to and including 52 kV

IEC 62271-103:2011 is applicable to three-phase, alternating current switches and switch-disconnectors for their switching function, having making and breaking current ratings, for indoor and outdoor installations, for rated voltages above 1 kV up to and including 52 kV and for rated frequencies from 162/3 Hz up to and including 60 Hz. This standard is also applicable to single-pole switches used on three phase systems. This standard cancels and replaces the third edition of IEC 60265-1, published in 1998. It constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60265-1:1998:
- the rated voltage of 52 kV is now included;
- the document is aligned with IEC 62271-1 and IEC 62271-100;
- addition of a test procedure for short-circuit making tests;
- introduction of notion of NSDD (non-sustained disruptive discharge) as defined in IEC 62271-1 and restrikes;
- new classes C1 and C2 for capacitive switching;
- new Annex A defining tolerances.
This publication is to be read in conjunction with IEC 62271-1:2007. The contents of the corrigendum of October 2013 have been included in this copy.

Appareillage à haute tension - Partie 103: Interrupteurs pour tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV

La CEI 62271-103:2011 est applicable aux interrupteurs et interrupteurs-sectionneurs à courant alternatif triphasé ayant des pouvoirs de coupure et de fermeture assignés, prévus pour l'installation à l'intérieur et à l'extérieur, de tension assignée supérieure à 1 kV et inférieure ou égales à 52 kV et de fréquences assignées allant de 16 2/3 Hz jusqu'à et y compris 60 Hz. La présente norme est également applicable aux interrupteurs unipolaires prévus pour des réseaux triphasés. La présente norme annule et remplace la troisième édition de la CEI 60265-1 parue en 1998. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à la CEI 60265-1:1998:
- la tension assignée de 52 kV est désormais comprise;
- le document est aligné avec la CEI 62271-1 et la CEI 62271-100;
- ajout d'une procédure d'essai pour les essais d'établissement de courant de court-circuit;
- introduction du concept de NSDD (décharge disruptive non soutenue) comme défini dans la CEI 62271-1 et des réamorçages;
- nouvelles classes C1 et C2 pour man uvre de charges capacitives;
- nouvelle Annexe A définissant les tolérances.
Cette publication doit être lue conjointement avec l'IEC 62271-1:2007. Le contenu du corrigendum d'octobre 2013 a été pris en considération dans cet exemplaire.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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 62271-103 has been prepared by subcommittee 17A: High-voltage

switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.

This standard cancels and replaces the third edition of IEC 60265-1, published in 1998. It

constitutes a technical revision.

This edition includes the following significant technical changes with respect to

IEC 60265-1:1998:
– the rated voltage of 52 kV is now included;
– the document is aligned with IEC 62271-1 and IEC 62271-100;
– addition of a test procedure for short-circuit making tests;

– introduction of notion of NSDD (non-sustained disruptive discharge) as defined in

IEC 62271-1 and restrikes;
– new classes C1 and C2 for capacitive s
