High-voltage switchgear and controlgear - Part 310: Electrical endurance testing for circuit-breakers above a rated voltage of 52 kV
This technical report IEC/TR 62271-310:2008 is applicable to class E2 circuit-breakers above a rated voltage of 52 kV and above intended for use on overhead lines. The test programmes are based on accumulated electrical stresses due to current interruption during a period of 25 years, which was chosen as representative for a maintenance-free interval. This second edition of IEC/TR 62271-310 cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- reduction of number tests in the wear stage;
- new definition of acceptance test for demonstration of end-of-life thermal interruption capability.
Appareillage à haute tension - Partie 310: Essais d'endurance électrique pour disjoncteurs de tension assignée supérieure à 52 kV
Ce rapport technique CEI/TR 62271 310:2008 s'applique à la classe E2 de disjoncteurs de tension assignée supérieure à 52 kV, prévus pour la manoeuvre de lignes aériennes. Les programmes d'essais sont basés sur des contraintes électriques cumulées dues à des interruptions de courant, durant une période de 25 ans, qui a été choisie comme représentative d'un intervalle de temps sans maintenance. Cette deuxième édition du CEI/TR 62271-310 annule et remplace la première édition parue en 2004. Elle constitue une révision technique. La présente édition inclut les modifications techniques significatives par rapport à l'édition précédente:
- réduction du nombre d'essais durant la période d'essais d'usure;
- nouvelle définition de l'essai d'acceptation pour démonstration de la capacité de coupure thermique de fin de vie.

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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC/TR 62271-310, which is a technical report, has been prepared by subcommittee 17A:
High-voltage switchgear and controlgear, of IEC technical committee 17: Switchgear and
controlgear.
This second edition of IEC/TR 62271-310 cancels and replaces the first edition published in
2004. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– reduction of number tests in the wear stage;
– 4 – TR 62271-310 © IEC:2008
– new definition of acceptance test for demonstration of end-of-life thermal interruption
capability.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
17A/803/DTR 17A/814/RVC
Full information on the voting for the approval of this technical report 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.
A list of all parts of IEC 62271 series, under the general title High-voltage switchgear and
controlgear can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or

INTRODUCTION
Based on experience with existing high-voltage circuit-breakers in service and with system
protection and maintenance policies, the majority of circuit-breaker applications are covered
by class E1 as defined in 3.4.112 of IEC 62271-100. No additional tests for extended
electrical endurance are required.
However, extended electrical endurance (class E2) as defined in 3.4.113 of IEC 62271-100
should be considered for the following reasons:
• Field experience collected so far by CIGRE is limited only for circuit-breaker designs
