Electromagnetic compatibility (EMC) - Part 3-11: Limits - Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems - Equipment with rated current ≤ 75 A and subject to conditional connection

NEW!IEC 61000-3-11:2017 is available as IEC 61000-3-11:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61000-3-11:2017 is concerned with the emission of voltage changes, voltage fluctuations and flicker produced by equipment and impressed on the public low-voltage supply system. It specifies the limits of voltage changes produced by equipment tested under specified conditions. This edition includes the following significant technical changes with respect to the previous edition: a) addition of a new Annex A which explains the limitations and effectiveness of IEC 61000‑3-11 regarding the connection of multiple items of similar equipment at the same location in the supply network.

Elektromagnetische Verträglichkeit (EMV) - Teil 3-11: Grenzwerte – Begrenzung von Spannungsänderungen, Spannungsschwankungen und Flicker in öffentlichen Niederspannungs-Versorgungsnetzen für Geräte mit einem Bemessungsstrom ≤ 75 A je Leiter, die einer Sonderanschlussbedingung unterliegen

NEW!IEC 61000-3-11:2017 est disponible sous forme de IEC 61000-3-11:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 61000-3-11:2017 traite des variations de tension, des fluctuations de tension et du papillotement (ou flicker) émis par des équipements et véhiculés par le réseau public d'alimentation basse tension. Elle spécifie les limites des variations de tension produites par des équipements soumis à l'essai dans des conditions déterminées. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) ajout d'une nouvelle Annexe A qui explicite les limites et l'efficacité de l'IEC 61000-3-11 concernant le raccordement de plusieurs équipements analogues au même emplacement dans le réseau d'alimentation.

Elektromagnetna združljivost (EMC) - 3-11. del: Mejne vrednosti - Omejitev vrednosti kolebanja napetosti in flikerja v nizkonapetostnih napajalnih sistemih - Oprema z naznačenim tokom <= 75 A, priključena pod posebnimi pogoji

Ta del standarda IEC 61000 se osredotoča na zahteve glede odpornosti ter preskusne metode za električno in elektronsko opremo pri obratovalnih pogojih v zvezi z naslednjim:
a) ponavljajoči se počasni pridušeni nihajni valovi, ki se pojavljajo predvsem v napajalnih, krmilnih in signalnih kablih v visokonapetostnih ter srednjenapetostnih (HV/MV) postajah;
b) ponavljajoči se hitri pridušeni nihajni valovi, ki se pojavljajo predvsem v napajalnih, krmilnih in signalnih kablih v s plinom izoliranih postajah (GIS) ter v nekaterih primerih tudi v z zrakom izoliranih postajah (AIS) ali v kateri koli inštalaciji zaradi pojava elektromagnetnih impulzov z velikih višin (HEMP).
Cilj tega dokumenta je vzpostaviti skupno in ponovljivo sklicevanje za oceno odpornosti električne ter elektronske opreme, podvržene pridušenim nihajnim valovom na napajalnih, signalnih, krmilnih in ozemljitvenih vratih. Preskusna metoda, dokumentirana v tem delu standarda IEC 61000, opisuje skladno metodo za oceno odpornosti opreme ali sistema proti opredeljenemu pojavu.
OPOMBA: To je osnovna objava o elektromagnetni združljivosti, ki jo uporabljajo tehnični odbori v okviru Mednarodne elektrotehniške komisije (IEC), kot je opisano v vodilu 107 Mednarodne elektrotehniške komisije.
Poleg tega je v vodilu 107 navedeno, da so tehnični odbori v okviru Mednarodne elektrotehniške komisije odgovorni za določitev morebitne uporabe tega standarda s preskusom odpornosti, v primeru uporabe pa so odgovorni za določitev ustreznih preskusnih ravni in meril učinkovitosti. 1
Dokument določa:
– preskusno napetost in valovno obliko toka;
– obseg preskusnih ravni;
– opremo za preskušanje;
– postopke za umerjanje in preverjanje preskusne opreme;
– postavitve za preskušanje;
– preskusni postopek.

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 independ

NACIONALNI PREDGOVOR
Evropski standard EN IEC 61000-3-11:2019 je pripravil tehnični odbor Evropskega komiteja za
standardizacijo v elektrotehniki CENELEC CLC/TC 210 Elektromagnetna združljivost (EMC). Slovenski
standard SIST EN IEC 61000-3-11:2019 je prevod evropskega standarda EN IEC 61000-3-11:2019. V
primeru spora glede besedila slovenskega prevoda v tem standardu je odločilen izvirni evropski
standard v angleškem jeziku. Slovensko izdajo standarda je pripravil tehnični odbor SIST/TC EMC –
Elektromagnetna združljivost.
Odločitev za privzem tega standarda je v novembru 2019 sprejel tehnični odbor SIST/TC EMC –
Elektromagnetna združljivost.
ZVEZE S STANDARDI
S privzemom tega evropskega standarda veljajo za omejeni namen referenčnih standardov vsi

SIST EN IEC 61000-3-11 : 2019
Dodatek ZA
(normativni)
Normativna sklicevanja na mednarodne publikacije z njihovimi ustreznimi
evropskimi publikacijami
Naslednji dokumenti so v besedilu navedeni tako, da del ali celotna njihova vsebina predstavlja zahteve
tega dokumenta. Pri datiranih sklicevanjih se uporablja zgolj navedena izdaja. Pri nedatiranih
sklicevanjih se uporablja zadnja izdaja navedenega dokumenta (vključno z vsemi dopolnili).

OPOMBA 1: Kadar je neka mednarodna publikacija spremenjena s skupno spremembo, označeno z (mod), je treba uporabiti
ustrezni EN/HD.
OPOMBA 2: Najnovejše informacije o najnovejših izdajah evropskih standardov, naštetih v tem dodatku, so na voljo tukaj:
