EN IEC 61869-9:2019

Instrument transformers - Part 9: Digital interface for instrument transformers

IEC 61869-9:2016(E) is a product family standard applicable to instrument transformers with digital output. The product standard is composed of IEC 61869-1 and IEC 61869-6, in addition to this standard and the relevant product specific standards in the IEC 61869 series (Part 7, Part 8, Part 12, Part 13, Part 14, and Part 15). This standard defines requirements for digital communications of instrument transformer measurements. It is based on the IEC 61850 series, UCA international users group document Implementation guideline for digital interface to instrument transformers using IEC 61850-9-2, and the relevant parts of IEC 60044-8 that are replaced by this standard. It includes additional improvements including the IEC 61588 network based time synchronization. This first edition replaces the corresponding specific requirements previously contained in IEC 60044-8, published in 2002. This International Standard contains specific requirements for electronic low power instrument transformers (LPIT) having a digital output. However, the reader is encouraged to use its most recent edition. This publication contains an attached file in the form of a .xml file. This file is intended to be used as a complement and does not form an integral part of the publication.

Messwandler - Teil 9: Digitale Schnittstelle für Messwandler

Transformateurs de mesure - Partie 9: Interface numérique pour les transformateurs de mesure

L'IEC 61869-9:2016 est une norme de familles de produits applicable aux transformateurs de mesure à sortie numérique. La norme de produit est composée de l'IEC 61869 1 et de l'IEC 61869 6, en plus de la présente norme et des normes spécifiques aux produits correspondants dans la série IEC 61869 (Partie 7, Partie 8, Partie 12, Partie 13, Partie 14 et Partie 15). La présente norme définit les exigences en matière de communication numérique des mesurages de transformateurs de mesure. Elle repose sur la série IEC 61850, sur le document Implementation guideline for digital interface to instrument transformers using IEC 61850-9-2 de l’UCA International Users Group et sur les parties correspondantes de l'IEC 60044-8 qui sont remplacées par la présente norme. Elle inclut des améliorations supplémentaires, notamment la synchronisation basée sur le réseau de l'IEC 61588. Cette première édition remplace les exigences spécifiques correspondantes de l'IEC 60044-8, parue en 2002. La présente Norme internationale contient les exigences spécifiques relatives aux transformateurs de mesure électroniques de faible puissance (LPIT) équipés d’une sortie numérique. La présente publication contient un fichier joint sous la forme de fichier .xml. Ce fichier est destiné à être utilisé en complément de la présente publication et n’en fait pas partie intégrante.

Instrumentni transformatorji - 9. del: Digitalni vmesnik za instrumentne transformatorje (IEC 61869-9:2016)

Ta del standarda IEC 61869 je standard družine izdelkov, ki se uporablja za merilne transformatorje z digitalnim izhodom. Standard za izdelek je sestavljen iz standardov IEC 61869-1 in IEC 61869-6 ter se uporablja poleg tega standarda in ustreznih standardov za posamezne izdelke iz skupine standardov IEC 61869 (7., 8., 12., 13., 14. in 15. del).
Ta standard določa zahteve za digitalne komunikacije meritev merilnih transformatorjev. Temelji na skupini standardov IEC 61850, dokumentu mednarodne skupine uporabnikov UCA Smernice za implementacijo digitalnega vmesnika do merilnega transformatorja ob uporabi standarda IEC 61850-9-2 in ustreznih delih standarda IEC 60044-8, ki jih nadomešča ta standard. Vključuje tudi dodatne izboljšave, vključno z omrežno časovno sinhronizacijo iz standarda IEC 61588.
