(Main)High-voltage switchgear and controlgear - Part 110: Inductive load switching
High-voltage switchgear and controlgear - Part 110: Inductive load switching
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 EN 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. Switching unloaded transformers, i.e. breaking transformer magnetizing current, is not considered in this standard. The reasons for this are as follows: a) due to the non-linearity of the transformer core, it is not possible to correctly model the switching of transformer magnetizing current using linear components in a test laboratory. Tests conducted using an available transformer, such as a test transformer, will only be valid for the transformer tested and cannot be representative for other transformers; b) as detailed in the guide for application of EN 62271-100 and EN 60694, the characteristics of this duty are usually less severe than any other inductive current switching duty. It should be noted that such a duty may produce severe overvoltages within the transformer winding(s) depending on the circuit-breaker re ignition behaviour and transformer winding resonance frequencies. Short-line faults, out-of-phase current making and breaking and capacitive current switching are not applicable to circuit-breakers applied to switch shunt reactors or motors. These duties are therefore not included in this standard.
Hochspannungs-Schaltgeräte und -Schaltanlagen - Teil 110: Schalten induktiver Lasten
Appareillage à haute tension - Partie 110: Manoeuvre de charges inductives
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 EN 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. La manoeuvre de transformateurs à vide, c'est-à-dire la coupure de courant magnétisant de transformateur, n'est pas prise en compte dans cette norme. Les raisons pour cela sont les suivantes: a) à cause du comportement non linéaire du circuit magnétique du transformateur, il n'est pas possible de modéliser correctement l'établissement et la coupure d'un courant magnétisant en utilisant des composants linéaires dans un laboratoire d'essais. Les essais effectués en utilisant un transformateur à disposition, tel qu'un transformateur d'essais, seront valables seulement pour le transformateur essayé et ne peuvent pas être représentatifs pour d'autres transformateurs; b) ainsi qu'il est détaillé dans le Guide d'application des EN 62271-100 et 60694, les caractéristiques de cette manoeuvre sont habituellement moins sévères que les autres manoeuvres d'établissement et de coupure de courants inductifs. Il convient de noter que cette manoeuvre peut produire des surtensions sévères dans le ou les bobinages d'un transformateur en fonction de la caractéristique de réallumage du disjoncteur et des fréquences de résonances du bobinage du transformateur. L'établissement et la coupure de défaut en ligne, courant de discordance de phases et courants capacitifs ne sont pas applicables aux disjoncteurs pour la manoeuvre de réactances shunt ou de

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 re
