20、technical 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
21、 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 Natio
22、nal 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 (I
23、SO) 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
24、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
25、 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. An
26、y 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 declared to be in conformity with an IEC Public
27、ation. 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, prope
28、rty 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 t
29、his 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
30、or all such patent rights. International Standard IEC 61000-2-13 has been prepared by subcommittee 77C: High power transient phenomena, of IEC technical committee 77: Electromagnetic compatibility. It has the status of a basic EMC publication in accordance with IEC Guide 107. The text of this standa
31、rd is based on the following documents: FDIS Report on voting 77C/153/FDIS 77C/155/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

At this date, the publication will be reco
33、nfirmed; withdrawn; replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 6 61000-2-13 IEC:2005(E) INTRODUCTION IEC 61000 is published in separate parts according to the following structure: Part 1: General General considerations (introduct

37、ETIC COMPATIBILITY (EMC) Part 2-13: Environment High-power electromagnetic (HPEM) environments Radiated and conducted 1 Scope This part of IEC 61000 defines a set of typical radiated and conducted HPEM environment waveforms that may be encountered in civil facilities. Such threat environments can pr
38、oduce damaging effects on electrical and electronic equipment in the civilian sector, as described in IEC 61000-1-5. It is necessary to define the radiated and conducted environments, in order to develop protection methods. For the purposes of this standard, high-power conditions are achieved when t
39、he peak electric field exceeds 100 V/m, corresponding to a plane-wave free-space power density of 26,5 W/m 2 . This criterion is intended to define the application of this standard to EM radiated and conducted environments that are substantially higher than those considered for “normal“ EMC applicat
40、ions, which are covered by the standards produced by IEC SC 77B. The HPEM environment can be: radiated or conducted; a single pulse envelope with many cycles of a single frequency (an intense narrowband signal that may have some frequency agility and the pulse envelope may be modulated); a burst con
41、taining many pulses, with each pulse envelope containing many cycles of a single frequency; an ultrawideband transient pulse (spectral content from tens of MHz to several GHz); a burst of many ultrawideband transient pulses. The HPEM signal could be from sources such as radar or other transmitters i
42、n the vicinity of an installation or from an intentional generator system targeting a civilian facility. Radiated signals can also induce conducted voltages and currents through the coupling process. In addition, conducted HPEM environments may also be directly injected into the wiring of an install
43、ation. There is a critical distinction between the HEMP (high-altitude electromagnetic pulse) environment and the HPEM environment, in terms of the range or the distance of the affected electrical or electronic components from the source. In the context of HEMP, the range is immaterial, as the HEMP
44、environment propagates downward from space to the earths surface and is therefore relatively uniform over distances of 1 000 km. On the other hand, in the HPEM context the environment and its effects decrease strongly with range. In addition, the HEMP waveshape is a series of time domain pulses whil
45、e the HPEM environment may have a wide variety of waveshapes. Consequently, the standardization process for HPEM environments is more difficult. The recommended approach is to investigate the various types of HPEM environments that have been produced to date and are likely to be feasible in the near
46、 future, and then to develop suitable HPEM standard waveforms from such a study. Such HPEM environment standard waveforms can be amended in due course, depending on emerging technologies that make it possible to produce them. 8 61000-2-13 IEC:2005(E) 2 Normative references The following referenced d
