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 is available as IEC TR 61850-90-7:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.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…

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 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…

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,…

This document specifies the composition, functional and performance requirements for a payload interface of civil unmanned aircraft systems (UAS), with the maximum take-off mass of 0,25 kg to 25 kg which relates to level II through IV according to ISO 21895. This document is applicable to the design and manufacture of physically independent payload interfaces which connect an external payload to…

1 Scope 1.1 Applicable equipment 1.1.1 Specific heaters This Standard applies to newly produced, direct-fired and indirect-fired construction heaters, hereinafter referred to as heaters, constructed entirely of new, unused parts and materials and primarily intended for temporary use in heating buildings or structures under construction, alteration, or repair. Products of combustion generated…
