EN 61000-3-3:2013

Electromagnetic compatibility (EMC) - Part 3-3: Limits - Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current <= 16 A per phase and not subject to conditional connection

NEW! IEC 61000-3-3:2013 is available as IEC Standards+ 61000-3-3:2013 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61000-3-3:2013 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. It is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection. IEC 61000-3-3 has the status of a product family standard within the IEC 61000 series. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision which takes account of the changes made in IEC 61000-4-15:2010.

Elektromagnetische Verträglichkeit (EMV) - Teil 3-3: Grenzwerte - Begrenzung von Spannungsänderungen, Spannungsschwankungen und Flicker in öffentlichen Niederspannungs-Versorgungsnetzen für Geräte mit einem Bemessungsstrom <= 16 A je Leiter, die keiner Sonderanschlussbedingung unterliegen

Compatibilité électromagnétique (CEM) - Partie 3-3: Limites - Limitation des variations de tension, des fluctuations de tension et du papillotement dans les réseaux publics d'alimentation basse tension, pour les matériels ayant un courant assigné <= 16 A par phase et non soumis à un raccordement conditionnel

NEW! La CEI 61000-3-3:2013 est disponible sous forme de IEC Standards+ 61000-3-3:2013 qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. La CEI 61000-3-3:2013 traite des limitations des fluctuations de tension et du papillotement (flicker) appliquées sur le réseau de distribution public basse tension. Elle spécifie les limites des variations de tension pouvant être produites par un équipement essayé dans des conditions spécifiées et formule des recommandations pour les méthodes d'évaluation. Elle s'applique aux matériels électriques et électroniques ayant un courant appelé inférieur ou égal à 16 A par phase et destinés à être raccordés à des réseaux publics de distribution basse tension présentant une tension nominale phase-neutre comprise entre 220 V et 250 V à 50 Hz et non soumis à un raccordement conditionnel. La CEI 61000-3-3 a le statut d'une norme de famille de produit au sein de la série CEI 61000. Cette troisième édition annule et remplace la seconde édition parue en 2008. Cette édition constitue une révision technique qui prend en compte les changements effectués dans la CEI 61000-4-15:2010.

Elektromagnetna združljivost (EMC) - 3-3. del: Mejne vrednosti - Omejitev vrednosti kolebanja napetosti in flikerja v nizkonapetostnih napajalnih sistemih za opremo z naznačenim tokom do 16 A in ni priključena pod posebnimi pogoji (IEC 61000-3-3:2013)

Ta del standarda IEC 61000 obravnava omejitev vrednosti kolebanja napetosti in flikerja v javnih nizkonapetostnih napajalnih sistemih. Določa omejitve vrednosti kolebanja napetosti, ki jih lahko proizvede oprema, preizkušena pod določenimi pogoji, in podaja smernice za metode ocenjevanja. Ta del standarda IEC 61000 se uporablja za električno in elektronsko opremo z vhodnim tokom do vključno 16 A na fazo, ki je namenjena za povezavo z javnimi nizkonapetostnimi razdelilnimi sistemi z napetostjo med linijskim in nevtralnim vodnikom od 220 V do 250 V pri 50 Hz ter ni priključena pod posebnimi pogoji. Če opremo, ki ni v skladu z omejitvami tega dela standarda IEC 61000, preskušate z referenčno impedanco Zref 6,4 in je zato ni mogoče razglasiti za skladno s tem delom, jo lahko znova preskusite oziroma ocenite, ali je skladna s standardom IEC 61000-3-11. Del 3-11 se uporablja za opremo z nazivnim vhodnim tokom ≤ 75 A na fazo in je priključena pod posebnimi pogoji. Preskusi po tem delu so tipski preskusi. Posebni preskusni pogoji so navedeni v dodatku A, preskusni krog pa je prikazan na sliki 1.

Evropski predgovor
Besedilo dokumenta 77A/809/FDIS, prihodnje 3. izdaje IEC 61000-3-3, ki ga je pripravil pododbor SC
77A "Nizkofrekvenčni pojavi" pri tehničnem odboru IEC/TC 77 "Elektromagnetna združljivost", je bilo
predloženo v vzporedno glasovanje IEC-CENELEC in ga je CENELEC sprejel kot EN 61000-3-3:2013.

Določena sta bila naslednja datuma:

 zadnji datum, do katerega mora EN dobiti status (dop) 2014-03-18
nacionalnega standarda bodisi z objavo istovetnega
besedila ali z razglasitvijo
(dow) 2016-06-18
 zadnji datum, ko je treba razveljaviti nacionalne
standarde, ki so z EN v nasprotju

Ta dokument nadomešča EN 61000-3-3:2008.

Standard EN 61000-3-3:2013 vključuje naslednje pomembne tehnične spremembe glede na EN 61000-
3-3:2008:
Ta izdaja upošteva spremembe, narejene v EN 61000-4-15:2011.

Opozoriti je treba na možnost, da bi lahko bil kateri od elementov tega dokumenta predmet patentnih
pravic. CENELEC ni odgovoren za identificiranje nobene od teh patentnih pravic.
Ta dokument je bil pripravljen v okviru mandata, ki sta ga Evropska komisija in Evropsko združenje za
prosto trgovino dala CENELEC, in podpira bistvene zahteve direktive (direktiv) EU.

Za zveze z direktivo (direktivami) EU glej informativni dodatek ZZ, ki je sestavni del tega dokumenta.

Razglasitvena objava
Besedilo mednarodnega standarda IEC 61000-3-3:2013 je CENELEC odobril kot evropski standard
brez kakršnihkoli sprememb.

Vključitev bistvenih zahtev direktiv EU

Ta evropski standard je bil pripravljen v okviru mandata, ki sta ga Evropska komisija in Evropsko
združenje za prosto trgovino dala CENELEC, in v obsegu svojega področja uporabe vključuje zaščitne
zahteve Priloge I, člena 1(a) Direktive 2004/108/ES in bistvene zahteve člena 3.1(b) (samo oddajanje)
Direktive 1999/5/ES.
Skladnost s tem standardom zagotavlja domnevo o skladnosti z določenimi bistvenimi zahtevami
zadevnih direktiv.
OPOMBA: Za proizvode, ki spadajo v področje uporabe tega standarda, se lahko uporabljajo druge zahteve in druge
direktive EU.
