Instrument transformers - Part 10: Additional requirements for low-power passive current transformers
IEC 61869-10:2017 is a product standard and covers only additional requirements for low-power passive current transformers. The product standard for low-power passive current transformers comprises IEC 61869-1, together with IEC 61869-6 and this document with specific requirements. This document is applicable to newly manufactured low-power passive current transformers with analogue output for use with electrical measuring instruments or electrical protective devices having a rated frequency from 15 Hz to 100 Hz. This document covers low-power passive current transformers used for measurement or protection and multi-purpose low-power passive current transformers used for both measurement and protection. This first edition of IEC 61869-10, together with IEC 61869-1, IEC 61869-6, IEC 61869-8 and IEC 61869-9, cancels and replaces the first edition of IEC 60044-8, published in 2002. This edition constitutes a technical revision. The technical changes concern IEC TC 38's decision to restructure the whole set of stand-alone standards in the IEC 60044 series and transform it into a new set of standards composed of general requirements documents and specific requirements documents.
Messwandler - Teil 10: Zusätzliche Anforderungen für Kleinsignal-Stromwandler
Transformateurs de mesure - Partie 10: Exigences supplémentaires concernant les transformateurs de courant passifs de faible puissance
L'IEC 61869-10:2017 est une norme de produit et couvre seulement les exigences supplémentaires concernant les transformateurs de courant passifs de faible puissance. La norme de produit sur les transformateurs de courant passifs de faible puissance est constituée de l'IEC 61869-1, à laquelle s'ajoutent l'IEC 61869-6 et le présent document portant sur les exigences spécifiques. Le présent document s'applique aux transformateurs de courant passifs de faible puissance à sortie analogique fabriqués récemment et destinés à être utilisés avec des appareils de mesure électriques ou des dispositifs électriques de protection présentant une fréquence assignée comprise entre 15 Hz et 100 Hz. Le présent document couvre les transformateurs de courant passifs de faible puissance utilisés pour la mesure ou la protection, ainsi que les transformateurs de courant passifs de faible puissance polyvalents utilisés à la fois pour la mesure et la protection. Cette première édition de l'IEC 61869-10 conjointement avec l'IEC 61869-1, l'IEC 61869-6, l'IEC 61869-8 et l'IEC 61869-9 annulent et remplacent la première édition de l'IEC 60044-8 publiée en 2002. Cette édition constitue une révision technique. Les révisions techniques concernent la décision du TC 38 de l'IEC de restructurer l'ensemble des normes indépendantes de la série IEC 60044 et d'en faire un nouvel ensemble de normes composé de documents portant sur les exigences générales et de documents portant sur des exigences spécifiques.
Instrumentni transformatorji - 10. del: Dodatne zahteve za pasivne tokovne transformatorje majhne moči (IEC 61869-10:2017)
Ta del standarda IEC 61869 je standard za izdelek in obsega le dodatne zahteve za pasivni tokovni transformator z nizko močjo. Standard za izdelek za pasivne tokovne transformatorje z nizko močjo sestavlja standard IEC 61869-1 skupaj s standardom IEC 61869-6 in tem dokumentom s specifičnimi zahtevami.
Ta dokument se uporablja za nove pasivne tokovne transformatorje z nizko močjo in analognim izhodom za uporabo z električnimi merilnimi instrumenti ali električnimi zaščitnimi napravami z nazivno frekvenco od 15 Hz do 100 Hz.
Ta dokument obsega pasivne tokovne transformatorje z nizko močjo, ki se uporabljajo za merjenje ali zaščito, in večnamenske pasivne tokovne transformatorje z nizko močjo, ki se uporabljajo tako za merjenje kot tudi za zaščito.
Podtočka 5.6.1001 obsega zahteve glede natančnosti, ki so potrebne za pasivne tokovne transformatorje z nizko močjo za uporabo z električnimi merilnimi inštrumenti.
Podtočka 5.6.1002 obsega zahteve glede natančnosti, ki so potrebne za pasivne tokovne transformatorje z nizko močjo za uporabo z električnimi varnostnimi releji in zlasti za oblike zaščite, pri katerih glavna zahteva določa vzdrževanje natančnosti do večkratnika naznačenega toka. Če je zahtevano, je v točki 5.6.1002 navedena natančnost prehodne napetosti pasivnih tokovnih transformatorjev z nizko močjo med okvaro.
Pasivni tokovni transformatorji z nizko močjo imajo le analogni napetostni izhod (za digitalni izhod ali za tehnologijo, ki uporablja kakršno koli vrsto aktivnih elektronskih komponent, glejte standard IEC 61869-82). Takšni pasivni tokovni transformatorji z nizko močjo lahko vključujejo sekundarni kabel za signal (kabel za prenos). Načelo delovanja pasivnega tokovnega transformatorja z odvedeno nizko močjo, ki uporablja tuljave z zračnim jedrom (tuljave Rogowski), je navedeno v Dodatku 10B, načelo delovanja pasivnih tokovnih transformatorjev s sorazmerno nizko močjo, ki uporablja tuljave z železnim jedrom in integriranim navitjem, je navedeno v Dodatku 10C.
