Shunt capacitors for A.C. power systems having a rated voltage above 1000 V - Part 4: Internal fuses

EN IEC 60871-4 applies to internal fuses which are designed to isolate faulty capacitor elements, in order to allow operation of the remaining parts of that capacitor unit and the bank in which the capacitor unit is connected. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank or any part thereof. The object of this part of IEC 60871 is to formulate requirements regarding performance and testing and to provide a guide for coordination of fuse protection.

Parallelkondensatoren für Wechselspannungs-Starkstromanlagen mit einer Bemessungsspannung über 1 000 V - Teil 4: Eingebaute Sicherungen

Condensateurs shunt pour réseaux à courant alternatif de tension assignée supérieure à 1 000 V - Partie 4: Fusibles internes

L'IEC 60871-4:2014 s'applique aux fusibles internes qui sont destinés à isoler les éléments de condensateur en défaut et permettre ainsi le maintien en service de la partie saine de l'unité et de la batterie à laquelle cette unité est raccordée. Ils ne sont pas destinés à se substituer à un dispositif de coupure, par exemple un disjoncteur ou une protection externe de la batterie de condensateurs ou une partie de celle-ci. La présente partie de l'IEC 60871 a pour objet de formuler des exigences relatives aux performances et aux essais et de fournir un guide pour la coordination de la protection par fusibles internes. Cette deuxième édition annule et remplace la première édition parue en 1996. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: Les exigences concernant la déconnexion ont été modifiées. Mots clés: fusibles internes, éléments de condensateur en défaut,  protection par fusibles internes

Vzporedni kondenzatorji za izmenične napajalne sisteme z naznačeno napetostjo nad 1000 V - 4. del: Notranje varovalke (IEC 60871-4:2014)

Standard EN IEC 60871-4 se nanaša na notranje varovalke, ki so namenjene izolaciji okvarjenih kondenzatorskih elementov, da bi se omogočilo delovanje preostalih delov take kondenzatorske enote in baterije, v katero je priključena kondenzatorska enota. Take varovalke niso nadomestek za stikalno napravo, kot je odklopnik, ali za zunanjo zaščito kondenzatorske baterije ali katerega koli njenega dela. Cilj tega dela standarda IEC 60871 je oblikovati zahteve glede zmogljivosti in preskušanja ter zagotoviti navodila za usklajevanje zaščite varovalk.

SHUNT CAPACITORS FOR AC POWER SYSTEMS
HAVING A RATED VOLTAGE ABOVE 1 000 V –

Part 4: Internal fuses

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 60871-4 has been prepared by IEC technical committee 33: Power
capacitors and their applications.
This second edition cancels and replaces the first edition published in 1996. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– The disconnecting requirements have been modified.
