(Main)Instrument transformers - Part 15: Additional requirements for voltage transformers for DC applications
Instrument transformers - Part 15: Additional requirements for voltage transformers for DC applications
IEC 61869-15:2018 provides all requirements specific to voltage transformers to be used in DC applications (DCVTs), whatever the technology used. The output signal can be analogue or digital. It is applicable to newly manufactured voltage transformers used for measuring, protection and/or control applications in DC power systems with a rated voltage above 1,5 kV. This document covers passive voltage dividers as well as active voltage transformers, used for measurement, control and protection. The general configuration of a single-pole low-power instrument transformer is described in Figure 601 of IEC 61869-6:2016. IEC 61869-15:2018 applies to voltage transformers (VT) intended to be used in DC applications with the following functions: • measure DC voltage (with significant harmonics); • withstand DC voltage. Two main technologies of DC converters exist today: LCC and VSC • Line-commutated converters (LCC) are based on thyristor converters. They are characterized by a single direction of current flow, and a voltage polarity reversal possibility. Significant voltage and current harmonics exist up to frequencies of about 3 kHz to 4 kHz. • Voltage source converters (VSC) are based on transistor converters. They are characterized by a bi-directional current flow and a single voltage polarity. Voltage and current harmonics exist up to frequencies of about 20 kHz.

Transformateurs de mesure - Partie 15: Exigences supplémentaires concernant les transformateurs de tension pour application en courant continu
IEC 61869-15:2018 couvre toutes les exigences particulières concernant les transformateurs de tension utilisés dans les applications en courant continu (transformateurs de tension pour courant continu), quelle que soit la technologie utilisée. Le signal de sortie peut être analogique ou numérique. Elle s'applique aux transformateurs de tension fabriqués récemment et utilisés pour des applications de mesure, de protection et/ou de commande sur des systèmes d'alimentation électrique en courant continu dont la tension assignée est supérieure à 1,5 kV. Le présent document couvre les diviseurs de tension passifs et les transformateurs de tension actifs utilisés à des fins de mesurage, de commande et de protection. La configuration générale d'un transformateur de mesure de faible puissance unipolaire est décrite à la Figure 601 de l'IEC 61869-6:2016. IEC 61869-15:2018 s'applique aux transformateurs de tension (VT, Voltage Transformer) destinés à être utilisés dans les applications en courant continu avec les fonctions suivantes: • mesurage de la tension continue (avec des harmoniques élevées); • tension continue de tenue. Il existe aujourd'hui deux principales technologies de convertisseur de courant continu: les convertisseurs commutés par le réseau (LCC, Line-Commutated Converter) et les convertisseurs de source de tension (VSC, Voltage Source Converter) • Les convertisseurs commutés par le réseau (LCC) sont basés sur les convertisseurs à thyristor. Ils se caractérisent par un flux de courant unidirectionnel et la possibilité d'inverser la polarité de la tension. Des harmoniques de tension et de courant élevées existent jusqu'à des fréquences d'environ 3 kHz à 4 kHz. • Les convertisseurs de source de tension (VSC) sont basés sur les convertisseurs à transistor. Ils se caractérisent par un flux de courant unidirectionnel et une polarité de tension unique. Des harmoniques de tension et de courant élevées existent jusqu'à des fréquences d'environ 20 kHz.
Instrumentni transformatorji - 15. del: Posebne zahteve za napetostne transformatorje (IEC 61869-15:2018)
Ta del standarda IEC 61869 podaja vse zahteve, specifične za napetostne transformatorje, ki se uporabljajo pri enosmernem toku (DCVT-je), ne glede na uporabljeno tehnologijo. Izhodni signal je lahko analogni ali digitalni.
Uporablja se za nove napetostne transformatorje, ki se uporabljajo za merjenje, zaščito in/ali nadzor v omrežjih enosmernega toka z nazivno napetostjo nad 1,5 kV.
Ta dokument zajema tako razdelilnike pasivne napetosti kot tudi transformatorje aktivne napetosti, ki se uporabljajo za nadzor in zaščito.
Splošna konfiguracija enopolnega nizkonapetostnega merilnega transformatorja je opisana na sliki 601 standarda IEC 61869-6:2016.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61869-15 has been prepared by IEC technical committee 38:
