L'IEC 62271-202:2022 spécifie les conditions de service, les caractéristiques assignées, les exigences structurelles générales et les méthodes d'essai applicables aux postes préfabriqués haute tension sous enveloppe. Ces postes préfabriqués sont connectés par câble à des réseaux haute tension à courant alternatif avec une tension de service inférieure ou égale à 52 kV et des fréquences…

2 SCOPE This standard applies to any products containing a claimed recycled plastic content of at least 5%, which is either credited according to the Chain of Custody (CoC) mass balance model or actual physical recycled content. This standard is not intended to determine the mechanical, physical and chemical qualities and properties of a product, nor the adequacy of the product’s constraint…

IEC TR 61850-90-7:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed…

IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER systems with a controllable power converter. The functions defined in this document…

This document discusses the physical limitations of probe and particle counter placement, and any tubing that connects the two, particularly in providing representative samples where particles 5 micrometres and greater are of interest. The document further identifies the key factors of sampling performance when classifying and monitoring, and good practice to determine and maintain an acceptable…

IEC 60939-2:2005+AMD1:2023 applies to passive filter units for electromagnetic interference suppression which fall within the scope of the Generic Specification IEC 60939-1. The scope of this Sectional specification is restricted to passive filter units for which safety tests are appropriate. This implies that filters specified according to this Sectional specification will either be connected to…

L'IEC 60939-2:2005+AMD1:2023 s’applique aux filtres passifs d’antiparasitage qui entrent dans le domaine d’application de la spécification générique IEC 60939-1. Le domaine d’application de la présente spécification intermédiaire est restreint aux filtres passifs pour lesquels des essais de sécurité sont appropriés. Par conséquent, les filtres spécifiés selon la présente spécification…

IEC TR 61850-90-27:2023, which is a Technical Report, is to provide basic aspects that need to be considered when using IEC 61850 for information exchange between systems and components to support applications for thermal systems connected to electric power networks. Thermal systems isolated from electric power networks are outside the scope of this document. From the perspective of category,…

IEC TS 62898-3-3:2023 deals with frequency and voltage stabilization of AC microgrids by dispatchable loads, which react autonomously on variations of frequency and voltage with a change in active power consumption. Both 50 Hz and 60 Hz electric power systems are covered. This document gives requirements to emulate the self-regulation effect of loads including synthetic inertia. The loads…
