IEC 61468:2021 applies to in-core neutron detectors, viz. self-powered neutron detectors (SPNDs), which are intended for application in systems important for nuclear reactor safety: protection, instrumentation and control. This document contains SPND characteristics and test methods. In this document, the main sources of errors, and the possibilities for their minimization are also considered.…

IEC 60794-1-403:2021 specifies a method of verifying that cable metallic elements are electrically continuous throughout the cable. Electrical continuity is important for bonding and grounding, toning for location, and other related system issues, and may represent a "goodness of manufacture" criterion. Typically, the test is one of continuity and carries no resistance or conductivity…

IEC 60794-1-403: 2021 spécifie une méthode permettant de vérifier que les éléments métalliques des câbles assurent la continuité électrique tout au long du câble. La continuité électrique est importante pour les liaisons équipotentielles et les mises à la terre, ainsi que pour la fonction de génération de tonalité permettant de localiser des câbles, et les autres problématiques associées au…

IEC 62934:2021 provides terms and definitions in the subject area of grid integration of renewable energy generation. The technical issues of grid integration mainly focus on the issues caused by renewable energy generation with variable sources and/or converter based technology, such as wind power and photovoltaic power generation. Some renewable energy generations such as hydro power and…

IEC 62934:2021 fournit des termes et définitions relatifs au domaine de l’intégration de la production d’énergie renouvelable aux réseaux électriques. Les questions techniques de l’intégration aux réseaux électriques portent principalement sur les problèmes causés par la production d’énergie renouvelable (par exemple, l’énergie éolienne et l’énergie photovoltaïque) à partir de sources variables…

IEC TR 61850-7-5:2021, which is a technical report, establishes modelling concepts that help the user to understand how to apply the models defined in IEC 61850-7-4 and IEC 61850-7-3 to implement practical applications. This document provides the basic concepts that are valid for all application domains using IEC 61850. Domain specific concepts are defined in other technical reports as in the…

IEC TR 63304:2021(E) describes the general principle and technical details of the methods of measurement of the DC magnetic properties of permanent magnet materials in an open magnetic circuit using a superconducting magnet (SCM). This method is applicable to permanent magnet materials, such as those specified in IEC 60404-8-1, the properties of which are presumed homogeneous throughout their…

IEC 62271-106:2021 applies to AC contactors and/or contactor-based controllers and motor-starters designed for indoor installation and operation at frequencies up to and including 60 Hz on systems having voltages above 1 kV and up to and including 24 kV. This document also includes additional requirements for outdoor installations where the equipment is housed in an additional protective…

L'IEC 62271-106:2021 s'applique aux contacteurs à courant alternatif et/ou aux combinés de démarrage à contacteurs et démarreurs de moteurs conçus pour des installations intérieures et pour fonctionner à des fréquences inférieures ou égales à 60 Hz, dans des réseaux de tensions supérieures à 1 kV, mais qui n'excèdent pas 24 kV. Le présent document comprend également des exigences…
