23、_ INSTRUMENT TRANSFORMERS Part 9: Digital interface for instrument transformers 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 promo

24、te 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 (

25、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

26、 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 possib

27、le, 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. Whil

28、e 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 t

29、o 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 attestatio

30、n 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 thi

31、s 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 ind

32、irect, 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 t

33、he 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 61869-9 has been pre

34、pared by IEC technical committee 38: Instrument transformers. This first edition replaces the corresponding specific requirements previously contained in IEC 60044-8, published in 2002. The text of this standard is based on the following documents: FDIS Report on voting 38/502/FDIS 38/508/RVD Full i

35、nformation on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC 61869-9:2016 IEC 2016 5 A list of all parts in the IEC 61869 series, published under

36、the general title Instrument transformers, can be found on the IEC website. 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. This International Standard contains specific req

37、uirements for electronic low power instrument transformers (LPIT) having a digital output. This Part 9 is to be read in conjunction with, and is based on, IEC 61869-1:2007, General Requirements and IEC 61869-6:2016. However, the reader is encouraged to use its most recent edition. This Part 9 follow

38、s the structure of IEC 61869-6 and IEC 61869-1 and supplements or modifies their corresponding clauses/subclauses. When a particular clause/subclause of Part 6 is not mentioned in this Part 9, that clause/subclause applies. When this standard states “addition”, “modification” or “replacement”, the r

39、elevant text in Part 6 is to be adapted accordingly. When a particular clause/subclause of Part 1 is not mentioned in Part 6, that clause/subclause applies. When part 6 states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. For additional clause

40、s, subclauses, figures, tables, annexes or note, the following numbering system is used: clauses, subclauses, tables, figures and notes that are numbered starting from 901 are additional to those in Part 1; additional annexes are lettered 9A, 9B, etc. An overview of the planned set of standards at t

IEC 61869-9:2016 IEC 2016 7 INTRODUCTION General This standard is a product family standard for instrument transforme

48、rs. It provides an application of the standard series IEC 61850, which details layered substation communication architecture in the world of instrument transformers. By providing tutorial material such as examples and explanations, it also provides access for instrument transformer, protective relay

49、 and meter experts to concepts and methods applied in the IEC 61850 series. Compared to instrument transformers, digital communication technology is subject to on-going changes which are expected to continue in the future. Significant experience with electronics integrated directly into instrument transformers has yet to be gathered on a broader basis, as this type of equipment is not widely spread in the industry and a change of paradigm has not yet occur
