Electromagnetic compatibility (EMC) - Part 4-18: Testing and measurement techniques - Damped oscillatory wave immunity test

This part of IEC 61000 focuses on the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, with regard to: a) repetitive slow damped oscillatory waves occurring mainly in power, control and signal cables installed in high voltage and medium voltage (HV/MV) substations; b) repetitive fast damped oscillatory waves occurring mainly in power, control and signal cables installed in gas insulated substations (GIS) and in some cases also air insulated substations (AIS) or in any installation due to high-altitude electromagnetic pulse (HEMP) phenomena. The object of this document is to establish a common and reproducible reference for evaluating the immunity of electrical and electronic equipment when subjected to damped oscillatory waves on supply, signal, control and earth ports. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. NOTE As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard is applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. 1 The document defines: – test voltage and current waveforms; – ranges of test levels; – test equipment; – calibration and verification procedures of test equipment; – test setups; – test procedure.

Compatibilité électromagnétique (CEM) - Partie 4-18: Techniques d'essai et de mesure - Essai d'immunité à l'onde oscillatoire amortie

IEC 61000-4-18: 2019 traite des exigences d'immunité et des méthodes d'essai des matériels électriques et électroniques dans des conditions d'exploitation, vis-à-vis: a) des ondes oscillatoires amorties lentes répétitives se manifestant principalement sur les câbles d’alimentation, de commande et de signal installés dans les postes à haute et à moyenne tension (HT/MT); b) des ondes oscillatoires amorties rapides répétitives se produisant principalement sur les câbles d'alimentation, de commande et de signal installés dans les postes métalliques sous enveloppes à isolation gazeuse (GIS) et dans certains cas également dans les postes à isolation par air (AIS) ou toute installation du fait des phénomènes d’impulsion électromagnétique à haute altitude (IEMN-HA). Le présent document a pour objet d'établir une référence commune reproductible dans le but d'évaluer l’immunité des matériels électriques et électroniques, quand ils sont soumis aux ondes oscillatoires amorties sur des accès d’alimentation, de signal, de commande et par les bornes de terre. La méthode d'essai documentée dans cette partie de l’IEC 61000 décrit une méthode logique en vue d'évaluer l'immunité d'un équipement ou d'un système vis-à-vis d'un phénomène donné.NOTE Comme décrit dans le Guide 107 de l’IEC, il s’agit d’une publication fondamentale en CEM pour une utilisation par les comités de produits de l’IEC. Comme indiqué également dans le Guide 107, les comités de produits de l’IEC sont chargés de déterminer si cette norme d’essai d’immunité est appliquée ou non. Si tel est le cas, il leur incombe de déterminer les niveaux d’essai et les critères d’aptitude à la fonction appropriés. Le document définit: la tension d'essai et les formes d'ondes de courant; les plages de niveaux d'essais; le matériel d'essai; les procédures d’étalonnage et de vérification du matériel d'essai; les montages d'essai; une procédure d’essai. Cette deuxième édition annule et remplace la première édition parue en 2006 et l'Amendement 1:2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) ajout d’une modélisation mathématique de la forme d’onde oscillatoire amortie; b) nouvelle Annexe B sur l’incertitude de mesure; c) ajout d’un CDN à grande vitesse; d) ajout des procédures d’étalonnage pour les CDN; e) ajout de l’utilisation de la pince de couplage capacitive sur les lignes d’interconnexion pour les ondes oscillatoires amorties rapides; f) ajout d’une procédure d'essai pour les convertisseurs continu/continu en cas de non-fonctionnement du CDN; g) nouvelle Annexe C sur les problèmes liés à l’alimentation des EUT équipés de convertisseurs continu/continu en entrée. Mots clés : exigences d'immunité et des méthodes d'essai des matériels électriques et électroniques Le contenu du corrigendum d'août 2019 a été pris en considération dans cet exemplaire.

Elektromagnetna združljivost (EMC) - 4-18. del: Preskusne in merilne tehnike - Preskus odpornosti proti nihajnemu valu

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.
