(Main)High-voltage switchgear and controlgear - Part 110: Inductive load switching
High-voltage switchgear and controlgear - Part 110: Inductive load switching
IEC 62271-110:2009 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation, for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1000 V and applied for inductive current switching with or without additional short-circuit current breaking duties. The standard is applicable to circuit-breakers in accordance with IEC 62271-100 that are used to switch high-voltage motor currents and shunt reactor currents and also to high-voltage contactors used to switch high-voltage motor currents. This second edition cancels and replaces the first edition dated 2005 and constitutes an editorial revision. The main changes from the first edition are that all references to IEC 60694 have been replaced by IEC 62271-1. This standard is to be read in conjunction with IEC 62271-1, first edition, published in 2007, and with IEC 62271-100, second edition, published in 2008.
This publication is to be read in conjunction with IEC 62271-1:2007 and IEC 62271-100:2008.
Appareillage à haute tension - Partie 110: Manoeuvre de charges inductives
La CEI 62271-110:2009 est applicable aux disjoncteurs à courant alternatif conçus pour une installation à l'intérieur ou à l'extérieur, et pour fonctionner à des fréquences de 50 Hz à 60 Hz, sur des réseaux de tensions supérieures à 1 000 V et prévus pour l'établissement et la coupure de courants inductifs avec ou sans pouvoir de coupure de court-circuit additionnel. Cette norme est applicable aux disjoncteurs selon CEI 62271-100 et qui sont utilisés pour l'établissement et la coupure de courants de moteurs à haute tension et de réactances shunt, et aussi aux contacteurs à haute tension utilisés pour l'établissement et la coupure de courants de moteurs à haute tension. Cette deuxième édition annule et remplace la première édition datée 2005, elle constitue en une révision rédactionnelle. Par rapport à la première édition toutes les références à la CEI 60694 ont été remplacées par la celles à la CEI 62271-1. Cette norme doit être lue en conjonction avec la CEI 62271-1, première édition, parue en 2007, et avec la CEI 62271-100, deuxième édition, parue en 2008.
Cette publication doit être lue conjointement avec la CEI 62271-1:2007 et la CEI 62271-100:2008.

HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Part 110: Inductive load switching
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 it
