SIST EN 61000-4-30:2015

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.

Elektromagnetische Verträglichkeit (EMV) - Teil 4-30: Prüf- und Messverfahren - Verfahren zur Messung der Spannungsqualität

Compatibilité Electromagnétique (CEM) -- Partie 4-30 : Techniques d'essai et de mesure - Méthodes de mesure de la qualité de l'alimentation

NEW! IEC 61000-4-30:2015 est disponible sous forme de IEC Standards+ 61000-4-30:2015 qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L'IEC 61000-4-30:2015 définit les méthodes de mesure des paramètres de qualité de l'alimentation des réseaux d'énergie électrique en courant alternatif à une fréquence fondamentale déclarée de 50 Hz ou 60 Hz et la façon d'interpréter les résultats. Les méthodes de  mesure sont décrites pour chaque paramètre applicable en des termes qui fournissent des résultats fiables et répétitifs indépendamment   de la mise en oeuvre de la méthode. La présente norme porte sur les méthodes de mesure destinées aux mesurages in situ. Le mesurage des paramètres couverts par la présente norme se limite aux phénomènes   conduits sur les réseaux d'énergie électrique. Les paramètres de qualité de l'alimentation pris en compte dans la présente norme sont la fréquence industrielle, l'amplitude de la tension d'alimentation, le papillotement ("flicker"), les creux et les surtensions temporaires d'alimentation, les coupures de tension, les tensions   transitoires, le déséquilibre de tension d'alimentation, les harmoniques et interharmoniques de tension, les signaux transmis  sur la tension d'alimentation, les variations rapides de tension et les mesurages de courant. Les émissions dans la plage comprise entre 2 kHz et 150 kHz sont prises en compte dans l'Annexe C (informative), et les valeurs hautes et valeurs basses sont prises en compte dans l'Annexe D (informative). En fonction de l'objet du  mesurage, les mesurages peuvent porter soit sur une partie des phénomènes de cette  liste, soit sur l'ensemble. Cette troisième édition annule et remplace la deuxième édition, parue en 2008. Cetteédition constitue une révision technique. Cette édition inclut les  modifications techniques majeures suivantes par rapport à l'édition précédente:
- la méthode de mesure du courant, précédemment informative, est désormais normative et comporte quelques modifications;
- la méthode de mesure de RVC (rapid voltage change - variations rapides de tension) a été ajoutée;
- la méthode de mesure des émissions conduites dans la plage de 2 kHz à 150 kHz a été ajoutée dans l'Annexe informative C;
- les paramètres de valeur basse et de valeur haute ont été déplacés dans l'Annexe informative D;
- les méthodes de mesure de Classe A et de Classe S sont définies et clarifiées, tandis que la Classe B a été déplacée dans l'Annexe informative E en vue d'un retrait ultérieur;
- les méthodes de mesure se poursuivent dans la présente Norme, mais les responsabilités pour les grandeurs d'influence, les performances et les procédures d'essai ont été transférées dans l'IEC 62586-2.

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.

SIST EN 61000-4-30 : 2015
NACIONALNI UVOD
Standard SIST EN 61000-4-30 (sl), Preskusne in merilne tehnike – Metode merjenja kakovosti napetosti
(IEC 61000-4-30:2015), 2015, ima status slovenskega standarda in je istoveten evropskemu standardu
EN 61000-4-30 (en), Electromagnetic Compatibility (EMC) – Part 4-30: Testing and measurement
techniques – Power quality measurement methods (IEC 61000-4-30:2015), 2015.
Ta standard nadomešča SIST EN 61000-4-30:2009.
NACIONALNI PREDGOVOR
Evropski standard EN 61000-4-30:2015 je pripravil tehnični odbor CLC/TC 210 Elektromagnetna zdru-
žljivost (EMC). Slovenski standard SIST EN 61000-4-30:2015 je prevod evropskega standarda EN
61000-4-30:2015. 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 septembru 2015 sprejel tehnični odbor SIST/TC EMC
Elektrmagnetna združljivost.
