EN IEC 61869-13:2021

Instrument transformers - Part 13: Stand-alone merging unit (SAMU)

IEC 61869-13:2021 is a product standard and covers only additional requirements for stand-alone merging units (SAMUs) used for AC applications having rated frequencies from 15 Hz to 100 Hz. The digital output format specification is not covered by this document; it is standardized in IEC 61869-9 as an application of IEC 61850, which specifies the power utility communication architecture. This document covers SAMUs having standardized analogue inputs (for example: 1 A, 5 A, 3,25 V / √3 or 100 V / √3) provided by instrument transformers compliant with relevant product standards (e.g. IEC 61869-2 to IEC 61869-5, IEC 61869-7, IEC 61869-8, IEC 61869-10, IEC 61869-11, IEC 60044-1 to IEC 60044-6, IEC 60185, IEC 60186, IEEE C57.13), and aims to convert them to the digital output compliant with IEC 61869-9. Other input and output types are outside the scope of this document. Appropriate SAMU functionality can be combined with switchgear controller functionality defined in IEC 62271-3 or other IED functionality defined in IEC 60255 (all parts). Cyber security requirements are outside the scope of this document and are covered by the IEC 62351 series. IEC 61869-13:2021 is to be used in conjunction with IEC 61869-9:2016, Digital interface for instrument transformers, and IEC 61869­6:2016, Additional general requirements for low-power instrument transformers, which, in turn, are based on IEC 61869-1:2007, General requirements.

Messwandler - Teil 13: Stand-alone Merging Unit (SAMU)

Transformateurs de mesure - Partie 13: Concentrateur autonome (SAMU)

L'IEC 61869-13:2021 est une norme de produits et ne couvre que les exigences supplémentaires pour les concentrateurs autonomes (SAMU) utilisés pour les applications en courant continu avec une fréquence assignée comprise entre 15 Hz et 100 Hz. Le présent document ne spécifie pas le format de sortie numérique. Celui-ci est normalisé par l'IEC 61869-9, en tant qu'application de l'IEC 61850, qui spécifie l'architecture de communication des services publics d'électricité. Le présent document couvre les SAMU dont les entrées analogiques sont normalisées (par exemple: 1 A, 5 A, 3,25 V / √3 ou 100 V / √3), fournies par des transformateurs de mesures conformes aux normes de produits pertinentes (par exemple IEC 61869-2 à IEC 61869-5, IEC 61869-7, IEC 61869-8, IEC 61869-10, IEC 61869-11, IEC 60044-1 à IEC 60044-6, IEC 60185, IEC 60186, IEEE C57.13), et vise à les convertir en sortie numérique conforme à l'IEC 61869-9. Les autres types d'entrées et de sorties sont hors du domaine d'application du présent document. La fonctionnalité SAMU adaptée peut être combinée à un appareillage de commande de distribution, défini dans l'IEC 62271-3, ou à d'autres fonctionnalités d'IED définies dans l'IEC 60255 (toutes les parties). Les exigences en matière de cybersécurité sont hors du domaine d'application du présent document et sont couvertes par la série IEC 62351. L'IEC 61869-13:2021 doit être lue conjointement avec l'IEC 61869-9:2016, Interface numérique des transformateurs de mesure, et l'IEC 61869­6:2016, Exigences générales supplémentaires concernant les transformateurs de mesure de faible puissance, qui sont elles-mêmes fondées sur l'IEC 61869-1:2007, Exigences générales.
