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
This part of IEC 61000 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. This part of IEC 61000 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. Equipment which does not comply with the limits of this part of IEC 61000 when tested with the reference impedance Zref of 6.4, and which therefore cannot be declared compliant with this part, may be retested or evaluated to show conformity with IEC 61000-3-11. Part 3-11 is applicable to equipment with rated input current ≤ 75 A per phase and subject to conditional connection. The tests according to this part are type tests. Particular test conditions are given in Annex A and the test circuit is shown in Figure 1.

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.

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
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.

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
1 Scope
This part of IEC 61000 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.
This part of IEC 61000 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.
Equipment which does not comply with the limits of this part of IEC 61000 when tested with
the reference impedance Z of 6.4, and which therefore cannot be declared compliant with
ref
this part, may be retested or evaluated to show conformity with IEC 61000-3-11. Part 3-11 is
applicable to equipment with rated input current ≤ 75 A per phase and subject to conditional
connection.
The tests according to this part are type tests. Particular test conditions are given in Annex A
and the test circuit is shown in Figure 1.
NOTE 1 The limits in this standard relate to the voltage changes experienced by consumers connected at the
interface between the public supply low-voltage network and the equipment user’s installation. Consequently, if the
actual impedance of the supply at the supply terminals of equipment connected within the equipment user’s
installation exceeds the test impedance, it is possible that supply disturbance exceeding the limits could occur.
NOTE 2 The limits in this standard are based mainly on the subjective severity of flicker imposed on the light from
230 V 60 W coiled-coil filament lamps by fluctuations of the supply voltage. For systems with nominal voltage less
than 220 V line to neutral and/or frequency of 60 Hz, the limits and reference circuit values are under
consideration.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
flicker
impression of unsteadiness of visual sensation induced by a light stimulus whose luminance
or spectral distribution fluctuates with time
[SOURCE: IEC 60050-161:1990, 161-08-13]
3.2
voltage change characteristic
d(t)
time function of the relative r.m.s. voltage change evaluated as a single value for each
successive half period between zero-crossings of the source voltage, except during time
intervals in which the voltage is in a steady-state condition for at least 1 s
Note 1 to entry: For detailed information about the evaluation of a voltage change characteristic and the definition
of a steady state condition see Annex C and IEC 61000-4-15:2010.
3.3

c
3.4
d
max
maximum absolute voltage change during an observation period
Note 1 to entry: For detailed information about the calculation of d see Annex C and IEC 61000-4-15:2010.
max
3.5
T
max
maximum time duration during the observation period that the voltage deviation d(t) exceeds
the limit for d
c
Note 1 to entry: During a voltage change characteristic the time duration T is accumulated until a new steady
max
state condition is established.
Note 2 to entry: The T limit evaluation in this standard is generally intended to evaluate the inrush current
max
pattern of the equipment under test. Thus, as soon as a new steady state condition is established, the T
max
evaluation is ended. When a new voltage change occurs that exceeds the limit for d , a new T evaluation is
c max
started. The maximum duration that d(t) exceeds the limit for d for any of the individual T evaluations during the
c max
observation period, is used for the comparison against the T limit, and is reported for the test.

MEDNARODNA ELEKTROTEHNIŠKA KOMISIJA
ELEKTROMAGNETNA ZDRUŽLJIVOST (EMC) –
3-3. del: Mejne vrednosti – Omejitev napetostnih sprememb, kolebanja napetosti in
flikerja v javnih nizkonapetostnih napajalnih sistemih za opremo z naznačenim tokom
do vključno 16 A in brez pogojne priključitve
Predgovor
1) IEC (Mednarodna elektrotehniška komisija) je svetovna organizacija za standardizacijo, ki združuje vse nacionalne
elektrotehnične komiteje (nacionalni komiteji IEC). Cilj IEC je pospeševati mednarodno sodelovanje v vseh vprašanjih
standardizacije s področja elektrotehnike in elektronike. V ta namen poleg drugih aktivnosti izdaja mednarodne standarde,
tehnične specifikacije, tehnična poročila, javnosti dostopne specifikacije (PAS) in vodila (v nadaljevanju: publikacije IEC). Za
njihovo pripravo so odgovorni tehnični odbori. Vsak nacionalni komite IEC, ki ga zanima obravnavana tema, lahko sodeluje v
tem pripravljalnem delu. Prav tako lahko v pripravi sodelujejo mednarodne organizacije ter vladne in nevladne ustanove, ki
so povezane z IEC. IEC deluje v tesni povezavi z mednarodno organizacijo za standardizacijo ISO skladno s pogoji,
določenimi v soglasju med obema organizacijama.
2) Uradne odločitve ali sporazumi IEC o tehničnih vprašanjih, pripravljeni v tehničnih odborih, v katerih so prisotni vsi nacionalni
komiteji, ki jih tema zanima, izražajo, kolikor je mogoče, mednarodno soglasje o obravnavani temi.
3) Publikacije IEC imajo obliko priporočil za njihovo uporabo na mednarodni ravni in jih kot takšne sprejmejo nacionalni komiteji
IEC. Čeprav IEC skuša na vse primerne načine zagotavljati točnost tehničnih vsebin v publikacijah IEC, IEC ne more biti
odgovoren za način, kako se določila uporabljajo, ter za morebitne napačne razlage končnih uporabnikov.
4) Da bi pospeševali mednarodno poenotenje, so se nacionalni komiteji IEC zavezali, da bodo v svojih nacionalnih in regionalnih
standardih čim pregledneje uporabljali mednarodne standarde. Vsako odstopanje med standardom IEC in ustreznim
nacionalnim ali regionalnim standardom je treba v slednjem jasno označiti.
5) IEC ni določil nobenega postopka označevanja, ki bi kazal na njegovo potrditev, in ne more biti odgovoren za katero koli
opremo, ki bi bila deklarirana kot skladna z eno od njegovih publikacij.
6) Vsi uporabniki naj bi si zagotovili zadnjo izdajo teh publikacij.
7) IEC ali njegovi direktorji, zaposleni, uslužbenci ali agenti, vključno s samostojnimi strokovnjaki ter člani tehničnih odborov in
nacionalnih komitejev IEC, ne prevzemajo nobene odgovornosti za kakršnokoli osebno poškodbo, škodo na premoženju ali
katerokoli drugo škodo kakršnekoli vrste, bodisi posredne ali neposredne, ali za stroške (vključno z zakonitim lastništvom) in
izdatke, povezane s publikacijo, njeno uporabo ali zanašanjem na to publikacijo IEC ali katerokoli drugo publikacijo IEC.
8) Pozornost je treba posvetiti normativnim virom, na katere se sklicuje ta publikacija. Uporaba navedenih publikacij je nujna za
pravilno uporabo te publikacije.
9) Opozoriti je treba na možnost, da bi lahko bil kateri od elementov tega mednarodnega standarda predmet patentnih pravic.
IEC ni odgovoren za identificiranje nobene od teh patentnih pravic.
Mednarodni standard IEC 61000-3-3 je pripravil pododbor SC 77A EMC – Nizkofrekvenčni pojavi pri
tehničnem odboru IEC/TC 77 Elektromagnetna združljivost.
Ta standard predstavlja 3-3. del iz skupine standardov IEC 61000. Ima status standarda za proizvod.

1 Področje uporabe
Ta del IEC 61000 obravnava omejevanje napetostnih sprememb in flikerja, ki so injicirani v javni
nizkonapetostni sistem napajanja.
Določa mejne vrednosti napetostnih sprememb, ki jih lahko proizvede oprema, preskušena v posebnih
pogojih, in daje napotek o metodah ocenjevanja.
Ta del IEC 61000 se uporablja za električno in elektronsko opremo z vhodnim tokom, enakim ali manjšim
od 16 A fazno, ki je namenjena priključitvi v javne nizkonapetostne distribucijske sisteme z napetostnim
območjem med 220 V in 250 V med linijskim in nevtralnim vodnikom pri 50 Hz in ni predmet pogojne
priključitve.
Oprema, ki pri preskušanju z referenčno impedanco Z iz 6.4 ni v skladu z mejnimi vrednostmi tega
ref
dela IEC 61000 in je zato ni mogoče razglasiti za skladno s tem delom, se lahko ponovno preskusi ali
ovrednoti, da se prikaže skladnost z IEC 61000-3-11. Del 3-11 se uporablja za opremo z naznačenim
vhodnim tokom do vključno 75 A na fazo in je predmet pogojne priključitve.
Preskusi po tem delu so preskusi tipa. Posebni preskusni pogoji so navedeni v dodatku A, preskusni
tokokrog pa je prikazan na sliki 1.
OPOMBA 1: Mejne vrednosti v tem standardu se nanašajo na spremembe napetosti, ki jih doživljajo uporabniki, priključeni na
točki vmesnika med javnim nizkonapetostnim omrežjem in inštalacijo uporabnika opreme. Če dejanska
impedanca napajalnega omrežja na napajalnih priključkih opreme, priključene znotraj inštalacije uporabnika
opreme, presega preskusno impedanco, je posledično mogoče, da pride v napajanju do motenj, ki presegajo
mejne vrednosti.
OPOMBA 2: Mejne vrednosti v tem standardu temeljijo predvsem na subjektivni jakosti flikerja, ki se superponira na svetlobo
žarnic s spiralno žarilno nitko 230 V 60 W s kolebanjem napajalne napetosti. Pri sistemih z nazivno napetostjo
pod 220 V med linijskim in nevtralnim vodnikom in/ali s frekvenco 60 Hz so mejne vrednosti in vrednosti
referenčnega tokokroga še v obravnavi.

3 Izrazi in definicije
V tem standardu veljajo naslednji izrazi in definicije:
3.1
fliker
vtis nestalnosti vidne zaznave, ki ga povzroča svetlobni dražljaj, katerega svetlost ali spektralna
porazdelitev se s časom spreminja
[VIR: IEC 60050-161:1990, 161-08-13]
3.2
karakteristika napetostne spremembe
d(t)
časovna funkcija relativne spremembe efektivne vrednosti napetosti, ovrednotena kot po ena vrednost
za vsako naslednjo polperiodo med prehodom napajalne napetosti skozi nič, razen med časovnimi
intervali, v katerih je napetost v ustaljenem stanju najmanj 1 sekundo
