30、rldwide 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
31、 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 su
32、bject 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
33、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 C
34、ommittees. 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 w
35、hich 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 Publi
36、cation 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
37、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 tech
38、nical 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
39、 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 subje
40、ct of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. This International Standard IEC 61869-3 has been prepared by subcommittee 38: Instrument transformers. This standard replaces IEC 60044-2: Inductive Voltage Transformers. The text of this standard i
41、s based on the following documents: FDIS Report on voting 38/410/FDIS 38/413/RVD Full information 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. 61
42、869-3 IEC:2011 5 This standard is Part 3 of IEC 61869, published under the general title Instrument transformers. This part 3 is to be read in conjunction with, and is based on, IEC 61869-1, General Requirements - first edition (2007)- however the reader is encouraged to use its most recent edition.
43、 This Part 3 follows the structure of IEC 61869-1 and supplements or modifies its corresponding clauses. When a particular clause/subclause of Part 1 is not mentioned in this Part 3, that clause/subclause applies as far as is reasonable. When this standard states “addition”, “modification” or “repla
44、cement”, the relevant text in Part 1 is to be adapted accordingly. For additional clauses, subclauses, figures, tables, annexes or notes, the following numbering system is used: clauses, subclauses, tables, figures and notes that are numbered starting from 301 are additional to those in Part 1; addi
45、tional annexes are lettered 3A, 3B, etc. An overview of the planned set of standards at the date of publication of this document is given below.
