(Main)Electromagnetic Compatibility (EMC) -- Part 4-30: Testing and measurement techniques - Power quality measurement methods
Electromagnetic Compatibility (EMC) -- Part 4-30: Testing and measurement techniques - Power quality measurement methods
This part of IEC 61000-4 defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz.
Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method’s implementation. This standard addresses measurement methods for in-situ measurements.
Measurement of parameters covered by this standard is limited to conducted phenomena in power systems. The power quality parameters considered in this standard are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics and interharmonics, mains signalling on the supply voltage, rapid voltage changes, and current measurements. Emissions in the 2 kHz to 150 kHz range are considered in Annex C (informative), and over- and underdeviations are considered in Annex D (informative).
Depending on the purpose of the measurement, all or a subset of the phenomena on this list may be measured.
NOTE 1 Test methods for verifying compliance with this standard can be found in IEC 62586-2.
NOTE 2 The effects of transducers inserted between the power system and the instrument are acknowledged but not addressed in detail in this standard. Guidance about effects of transducers can be found IEC TR 61869-103.

Elektromagnetna združljivost (EMC) - 4-30. del: Preskusne in merilne tehnike - Metode merjenja kakovosti napetosti (IEC 61000-4-30:2015)
Ta del standarda IEC 61000-4 določa metode za merjenje in interpretacijo rezultatov za parametre kakovosti napetosti v napajalnih sistemih z izmeničnim tokom in deklarirano osnovno napetostjo 50/60 Hz.
Za vsak ustrezen parameter so opisane merilne metode, ki zagotavljajo zanesljive in ponovljive rezultate ne glede na uvedbo posamezne metode. Ta standard obravnava merilne metode za meritve na mestu uporabe.
Meritve parametrov, ki jih zajema ta standard, so omejene na vodene pojave v napajalnih sistemih. Parametri kakovosti napetosti, obravnavani v tem standardu, so omrežna frekvenca, magnituda napajalne napetosti, nihanja, napetostni upadi in udari, motnje napetosti, prehodne napetosti, neravnovesje napajalne napetosti, napetostni harmoniki in medharmoniki, napetostni signali v omrežju, nenadne spremembe napetosti in meritve toka. Emisije v razponu 2–150 kHz so obravnavane v dodatku C (informativne vrednosti), odkloni navzgor in navzdol pa so obravnavani v dodatku D (informativne vrednosti). Odvisno od namena meritev se lahko izmerijo vrednosti vseh pojavov ali izbranega podnabora pojavov na tem seznamu.
OPOMBA 1: Preskusne metode za preverjanje skladnosti s tem standardom so navedene v standardu IEC 62586-2.
OPOMBA 2: Učinki pretvornikov, nameščenih med napajalni sistem in instrument, so v tem standardu upoštevani,
vendar niso podrobno obravnavani. Smernice glede učinkov pretvornikov so navedene v standardu IEC TR 61869-103.

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 61000-4-30 has been prepared by subcommittee 77A: EMC –
Low- frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
This standard forms part 4-30 of IEC 61000. It has the status of a basic EMC publication in

This part of IEC 61000-4 defines the methods for measurement and interpretation of results
for power quality parameters in a.c. power supply systems with a declared fundamental
frequency of 50 Hz or 60 Hz.
Measurement methods are described for each relevant parameter in terms that give reliable
and repeatable results, regardless of the method’s implementation. This standard addresses
measurement methods for in-situ measurements.
Measurement of parameters covered by this standard is limited to conducted phenomena in
power systems. The power quality parameters considered in this standard are power
frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-161, as well
as the following apply.
3.1
channel
individual measurement path through an instrument
Note 1 to entry: “Channel” and “phase” are not the same. A voltage channel is by definition the difference in
potential between 2 conductors. Phase refers to a single conductor. On polyphase systems, a channel may be
between 2 phases, or between a phase and neutral, or between a phase and earth, or between neutral and earth.
3.2
declared input voltage
U
din
value obtained from the declared supply voltage by a transducer ratio
3.3
declared supply voltage
U
c
normally the nominal voltage U of the system.
n
Note 1 to entry: If by agreement between the supplier and the customer a voltage different from the nominal
voltage is applied to the terminals, then this voltage is the declared supply voltage U
c.
3.4
dip threshold
voltage magnitude specified for the purpose of detecting the start and the end of a voltage
dip
3.5
flagged data
for any measurement time interval in which interruptions, dips or swells occur, the marked
measurement results of all other parameters made during this time interval
Note 1 to entry: For some applications, this ‘marked’ or ‘flagged’ data may be excluded from further analysis, for
example. See 4.7 for further explanation.
3.6
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]
3.6.1
P
st
short-term flicker evaluation based on an observation period of 10 min
– 12 – IEC 61000-4-30:2015 © IEC 2015
[SOURCE: IEC 61000-4-15]
3.6.2
P
lt
long-term flicker evaluation
[SOURCE: IEC 61000-4-15]
3.7
fundamental component
component whose frequency is the fundamental frequency
3.8
fundamental frequency
frequency in the spectrum obtained from a Fourier transform of a time function, to which all
the frequencies of the spectrum are referred
Note 1 to entry: In case of any remaining risk of ambiguity, the fundamental frequency may be derived from the
number of poles and speed of rotation of the synchronous generator(s) feeding the system.
3.9
harmonic component
any of the components having a harmonic frequency
Note 1 to entry: Its value is normally expressed as an r.m.s value. For brevity, such component may be referred
to simply as a harmonic.
[SOURCE: IEC 61000-2-2:2002, 3.2.4,]
3.10
harmonic frequency
frequency which is an integer multiple of the fundamental frequency
Note 1 to entry: The ratio of the harmonic frequency to the fundamental frequency is the harmonic order
(recommended notation: n) (IEC 61000-2-2:2002, 3.2.3).
3.11
hysteresis
difference in magnitude between the start and end thresholds
Note 1 to entry: This definition of hysteresis is relevant to PQ measurement parameters and is different from the
IEC 60050 definition which is relevant to iron core saturation.
Note 2 to entry: The purpose of hysteresis in the context of PQ measurements is to avoid counting multiple
events when the magnitude of the parameter oscillates about the threshold level.
3.12
influence quantity
quantity which is not the subject of the measurement and whose change affects the
relationship between the indication and the result of the measurement
[SOURCE: IEC 60050-311:2001, 311-06-01]
3.13
interharmonic component
spectral component with a frequency between two consecutive harmonic frequencies
Note 1 to entry: The definition is derived from IEC 61000-4-7.
Note 2 to entry: Its value is normally expressed as an r.m.s value. For brevity, such a component may be referred
to simply as an interharmonic.

Predgovor k mednarodnemu standardu
1) Mednarodna elektrotehniška komisija (IEC) je svetovna organizacija za standardizacijo, ki združuje vse nacionalne elektro-
tehniške 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 specifi-
kacije, tehnična poročila, javno 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, kjer 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 mednarodno uporabo in jih kot takšne sprejmejo nacionalni komiteji IEC. Čeprav
IEC skuša na vse primerne načine zagotavljati natančnost 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 se pospeševalo mednarodno poenotenje, so nacionalni komiteji IEC v svojih nacionalnih in regionalnih standardih dolžni
čim pregledneje uporabljati mednarodne standarde. Vsako odstopanje med standardom IEC in ustreznim nacionalnim ali
regionalnim standardom je treba v slednjem jasno označiti.
5) IEC sam ne izvaja potrjevanja skladnosti. Storitve ugotavljanja skladnosti in na nekaterih območjih tudi dostop do znakov
skladnosti IEC izvajajo neodvisni certifikacijski organi. IEC ne prevzema nikakršne odgovornosti za storitve, ki jih izvajajo
neodvisni certifikacijski organi.
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 kakršno koli osebno poškodbo, škodo na premoženju ali
katero koli drugo škodo kakršne koli 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 katero koli 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 61000-4-30 je pripravil pododbor 77A EMC – nizkofrekvenčni pojavi pri
tehničnem odboru IEC/TC 77 Elektromagnetna združljivost.
Ta standard je 4-30. del standarda IEC 61000. Ima status osnovne publikacije o EMC v skladu z IEC
Guide 107.
Ta tretja izdaja preklicuje in nadomešča drugo izdajo, objavljeno leta 2008. Predstavlja tehnično
spremembo.
Ta izdaja vključuje naslednje pomembne tehnične spremembe glede na predhodno izdajo:
a) metoda za merjenje toka, ki je bila predhodno informativna, je sedaj normativna z nekaterimi
spremembami;
b) dodana je merilna metoda za RVC (naglo spremembo napetosti);
c) merilna metoda za prevajano oddajanje v območju 2 kHz do 150 kHz je dodana v informativni
dodatek C;
d) parametri za pododmik in nadodmik so prestavljeni v informativni dodatek D;
SIST EN 61000-4-30 : 2015
e) določeni in razjasnjeni sta merilni metodi za razred A in razred S, medtem ko je razred B prestavljen
v informativni dodatek E in predviden za poznejšo odstranitev;
f) merilne metode so še vedno vključene v ta standard, toda odgovornost za vplivne veličine,
zmogljivost in preskusni postopki so preneseni v IEC 62586-2.
Besedilo tega standarda je osnovano na naslednjih dokumentih:
FDIS Poročilo o glasovanju
