IEC 62217:2012

Polymeric HV insulators for indoor and outdoor use - General definitions, test methods and acceptance criteria

IEC 62217:2012 is applicable to polymeric insulators whose insulating body consists of one or various organic materials. Polymeric insulators covered by this standard include both solid core and hollow insulators. They are intended for use on HV overhead lines and in indoor and outdoor equipment. The object of this standard is:
- to define the common terms used for polymeric insulators;
- to prescribe common test methods for design tests on polymeric insulators;
- to prescribe acceptance or failure criteria, if applicable.
These tests, criteria and recommendations are intended to ensure a satisfactory life-time under normal operating and environmental conditions. This standard shall only be applied in conjunction with the relevant product standard. This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision. This edition includes a significant technical change with respect to the previous edition. The first edition of IEC 62217 (2005) included two other alternative tracking and erosion tests (a 5 000 hour multi-stress test and a tracking wheel test) which were based on tests developed by CIGRE and utilities. These tests are no longer given as normative alternatives following the results of a study/questionnaire by TC 36 on the relative merits of all three tracking and erosion tests. The 5 000 hour multi-stress test and a tracking wheel test are described in IEC/TR 62730 (2012).

Isolateurs polymériques à haute tension pour utilisation à l'intérieur ou à l'extérieur - Définitions générales, méthodes d'essai et critères d'acceptation

La CEI 62217:2012 est applicable aux isolateurs polymériques dont le corps isolant se compose d'un ou de divers matériaux organiques. Les isolateurs polymériques traités dans la présente norme comprennent à la fois les isolateurs à fût plein et les isolateurs creux. Ils sont destinés à être utilisés sur des lignes aériennes HT et dans les appareils pour utilisation à l'intérieur ou à l'extérieur. L'objet de la présente norme est le suivant:
- définir les termes communs utilisés pour les isolateurs polymériques;
- prescrire des méthodes d'essai communes pour les essais de conception sur les isolateurs polymériques;
- prescrire des critères d'acceptation ou de défaillance, le cas échéant.
Ces essais, critères et recommandations sont destinés à assurer une durée de vie satisfaisante dans des conditions normales de fonctionnement et d'environnement. La présente norme ne doit être appliquée que conjointement avec la norme de produit applicable. Cette deuxième édition annule et remplace la première édition publiée en 2005. Cette édition constitue une révision technique. Cette édition inclut un changement technique significatif par rapport à l'édition précédente. La première édition de la CEI 62217 (2005) incluait deux autres essais alternatifs de cheminement et d'érosion (un essai de 5 000 heures sous contraintes multiples et un essai de roue d'endurance) qui étaient basés sur des essais développés par le CIGRE et les compagnies d électricité. Ces essais ne sont plus donnés comme alternatives normatives suite aux résultats d'une étude/questionnaire du comité d'études 36 sur les mérites relatifs des trois essais de cheminement et d'érosion. L'essai de 5 000 heures sous contraintes multiples et un essai de roue d'endurance sont décrits dans le rapport technique IEC/TR 62730 (2012).

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 62217 has been prepared by IEC technical committee 36:
Insulators.
This second edition cancels and replaces the first edition published in 2005. This edition
constitutes a technical revision.
