FprEN IEC 61869-1:2023

Instrument transformers - Part 1: General requirements

IEC 61869-1:2023 is applicable to newly manufactured instrument transformers intended for applications where the nominal voltage is higher than 1 kV AC or 1,5 kV DC, with an analogue or a digital secondary signal for measuring, protection and control purposes, with rated frequencies from 15 Hz to 400 Hz, or for DC applications. The general requirements for instrument transformers for applications in LV systems (nominal voltage ≤ 1 kV AC or ≤ 1,5 kV DC) are covered by IEC 61869-201. This part of IEC 61869 is a product family standard and covers general requirements only. For each type of instrument transformer, the product standard is composed of this document and the relevant specific product standard. This part of IEC 61869 contains the requirements for the limits of the errors both for analogue and digital secondary signal. The other characteristics of a digital interface for instrument transformer are standardised in IEC 61869-9 as an application of the IEC 61850 horizontal standard series, covering communication networks and systems for power utility automation. This part of IEC 61869 considers bandwidth requirements. The accuracy requirements on harmonics and requirements for the anti-aliasing filter are specified in 5.7. IEC 61869-1:2023 cancels and replaces the first edition published in 2007 and IEC 61869 6:2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) merger with IEC 61869-6:2016; b) new scope: equipment for HV applications with a nominal voltage > 1 kV AC or 1,5 kV DC; c) new classification of some special tests as type tests or routine test; d) additional type tests, additional special tests and new clause for commissioning tests; e) new annexes E, F, G and I.

Messwandler - Teil 1: Allgemeine Anforderungen

Transformateurs de mesure - Partie 1: Exigences générales

L'IEC 61869-1:2023 s’applique aux transformateurs de mesure récemment fabriqués destinés à des applications dont la tension nominale est supérieure à 1 kV en courant alternatif ou à 1,5 kV en courant continu, qui utilisent un signal secondaire analogique ou numérique à des fins de mesure, de protection et de commande, avec des fréquences assignées comprises entre 15 Hz et 400 Hz, ou à des applications en courant continu. Les exigences générales concernant les transformateurs de mesure destinés à des applications dans les réseaux BT (tension nominale ≤ 1 kV en courant alternatif ou ≤ 1,5 kV en courant continu) sont couvertes par l’IEC 61869-201. La présente partie de l’IEC 61869 est une norme de famille de produits et couvre uniquement les exigences générales. Pour chaque type de transformateur de mesure, la norme de produit se compose du présent document et de la norme de produit spécifique appropriée. La présente partie de l’IEC 61869 contient les exigences relatives aux limites d’erreurs, tant pour le signal secondaire analogique que pour le signal secondaire numérique. Les autres caractéristiques d’une interface numérique d’un transformateur de mesure sont normalisées dans l’IEC 61869-9 en tant qu’application de la série de normes horizontales IEC 61850, couvrant les réseaux et les systèmes de communication pour l’automatisation des systèmes électriques. La présente partie de l’IEC 61869 traite des exigences relatives à la largeur de bande. Les exigences de précision concernant les harmoniques et les exigences relatives au filtre antirepliement sont spécifiées en 5.7. L'IEC 61869-1:2023 annule et remplace la première édition publiée en 2007 et l’IEC 61869‑6:2016. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) fusion avec l’IEC 61869-6:2016; b) nouveau domaine d’application: matériel pour les applications HT avec une tension nominale > 1 kV en courant alternatif ou 1,5 kV en courant continu; c) nouvelle classification de certains essais spéciaux en essais de type ou en essais individuels de série; d) essais de type supplémentaires, essais spéciaux supplémentaires et nouvel article pour les essais de mise en service; e) nouvelles Annexes E, F, G et I.
