IEEE is a registered trademark in the U.S. Patent any IEC National Committee interested in the subject
3、 dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of the IEEE Standards A
4、ssociation (IEEE-SA) Standards Board. IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily
5、 members of IEEE and serve without compensation. While IEEE administers the process and establishes rules to promote fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of IEEE Sta
6、ndards documents is wholly voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers (see http:/standards.ieee.org/IPR/disclaimers.html for more information). IEC collaborates closely with IEEE in accordance with conditions determined by agreement betwee
7、n the two organizations. This Dual Logo International Standard was originally an IEEE standard that was adopted by the IEC and has been jointly revised by the IEC and IEEE under the terms of that agreement. 2) The formal decisions of IEC on technical matters express, as nearly as possible, an intern
8、ational consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. The formal decisions of IEEE on technical matters, once consensus within IEEE Societies and Standards Coordinating Committees has been reached, is dete
9、rmined by a balanced ballot of materially interested parties who indicate interest in reviewing the proposed standard. Final approval of the IEEE standards document is given by the IEEE Standards Association (IEEE-SA) Standards Board. 3) IEC/IEEE Publications have the form of recommendations for int
10、ernational use and are accepted by IEC National Committees/IEEE Societies in that sense. While all reasonable efforts are made to ensure that the technical content of IEC/IEEE Publications is accurate, IEC or IEEE cannot be held responsible for the way in which they are used or for any misinterpreta
11、tion by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications (including IEC/IEEE Publications) transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC/IEEE Publicati
12、on and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC and IEEE do not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC and IEE
13、E are 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 IEEE or its directors, employees, servants or agents including individual experts and membe
14、rs of its technical committees and IEC National Committees, or volunteers of IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board, for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indi
15、rect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC/IEEE Publication or any other IEC or IEEE Publications. 8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is indispe
16、nsable for the correct application of this publication. 9) Attention is drawn to the possibility that implementation of this IEC/IEEE Publication may require use of material covered by patent rights. By publication of this standard, no position is taken with respect to the existence or validity of a
17、ny patent rights in connection therewith. IEC or IEEE shall not be held responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of Patent Claims or determining whether any licensing terms or conditions provide
18、d in connection with submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their
19、own responsibility. 6 IEC 60255-24:2013 IEEE Std C37.111-2013 Published by IEC under license from IEEE. 2013 IEEE. All rights reserved. International Standard IEC 60255-24/IEEE Std C37.111 has been jointly revised by the Power System Relaying Committee of the IEEE Power and Energy Society 1in cooper
20、ation with IEC Technical Committee 95: Measuring relays and protection equipment, under the IEC/IEEE Dual Logo Agreement. This second edition cancels and replaces the first edition published in 2001 and constitutes a technical revision. The main changes with respect to the previous edition are as fo
21、llows: a) The new edition allows single file format (with extension .CFF) in lieu of four separate files. b) The single file with .CFF extension contains four sections of information corresponding to .CFG, .INF, .HDR, and .DAT. The DAT section is either in ASCII or Binary. c) The following additiona
22、l data file types are also supported: binary32 (using 4 bytes to represent integer numbers) and float32 (using 4 bytes to represent real numbers). d) The conguration (.CFG) le/section has been modied. Four new fields have been added at the end of the .CFG file/section in two separate lines. Two fiel
23、ds represent the time information and the time difference between local and UTC time, and these two fields comprise one line. Another two fields represent the time quality of samples and comprise the last line of the file/section. e) Some of the fields in the Conguration (.CFG) le/section have been
24、designated critical instead of non-critical. f) The use of Unicode UTF-8 characters has been added. However and because of the extensive use of the terms ASCII and Text throughout this document, any occurrence of these terms also inherently implies Unicode UTF-8. The text of this standard is based o
25、n the following IEC documents: FDIS Report on voting 95/308/FDIS 95/311/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. International standards are drafted in accordance with the ISO/IEC Directives, Part 2. The I
26、EC Technical Committee and IEEE Technical Committee have decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be rec
27、onfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 1A list of IEEE participants can be found at the following URL: http:/standards.ieee.org/downloads/C37/C37.111-2013/C37.111-2013_wg-participants.pdf
