29、irements 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 standardizati
30、on 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 en
31、trusted 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 Int
32、ernational 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 sinc
33、e 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
34、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 i
35、n 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment d
36、eclared to be in conformity with an IEC Publication. 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 Nati
37、onal 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 i
38、s 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 shal
39、l not be held responsible for identifying any or all such patent rights. International Standard IEC 60255-26 has been prepared by IEC technical committee 95: Measuring relays and protection equipment. This third edition cancels and replaces the second edition published in 2008. This third edition al
40、so cancels and replaces the following standards: IEC 60255-22-1:2007, IEC 60255-22-2:2008; IEC 60255-22-3:2007, IEC 60255-22-4:2008, IEC 60255-22-5:2008, IEC 60255-22-6:2001 and IEC 60255-22-7:2003, IEC 60255-11:2008, IEC 60255-25:2000 and IEC 60255-26:2008. This edition constitutes a technical revi
41、sion. This edition includes the following significant technical changes with respect to the previous edition: a) definition of test specifications, test procedures and acceptance criteria per phenomena and port under test in one document; b) extension of radiated emission measurement for frequencies
42、 above 1 GHz; c) limitation of radiated emission measurement at 3 m distance for small equipment only; d) addition of zone A and zone B test level on surge test; 60255-26 IEC:2013 5 e) extension of tests on the auxiliary power supply port by a.c. and d.c. voltage dips, a.c. component in d.c. (ripple
43、) and gradual shut-down / start-up; f) harmonization of acceptance criteria for immunity tests. The text of this standard is based on the following documents: FDIS Report on voting 95/309/FDIS 95/312/RVD Full information on the voting for the approval of this standard can be found in the report on v
44、oting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 60255 series, published under the general title Measuring relays and protection equipment, can be found on the IEC website. The committee has de
45、cided that the contents of this publication will remain unchanged until the maintenance result 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 reconfirmed; withdrawn; replaced by a revised edition
46、, or amended. 6 60255-26 IEC:2013 INTRODUCTION This part of the IEC 60255 series specifies all of the requirements for electromagnetic compatibility in a single document. As such, it is considered as an overview document for measuring relays and protection equipment. The detailed test procedures are
47、 given in other referenced standards. This part of IEC 60255 does not include the reversal of d.c. power supply polarity test which had been provided in IEC 60255-11, because this is a safety test. This test will be covered by future IEC 60255-27. 60255-26 IEC:2013 7 MEASURING RELAYS AND PROTECTION
48、EQUIPMENT Part 26: Electromagnetic compatibility requirements 1 Scope 1.1 General This part of the IEC 60255 series is applicable to measuring relays and protection equipment, taking into account combinations of devices to form schemes for power system protection including the control, monitoring, c
49、ommunication and process interface equipment used with those systems. This standard specifies the requirements for electromagnetic compatibility for measuring relays and protection equipment. Tests specified in this standard are not required for equipment not incorporating electronic circuits, for example electromechanical relays. The requirements specified in this standard are
