13、 5 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ELECTROMAGNETIC COMPATIBILITY (EMC) Part 6-6: Generic standards HEMP immunity for indoor equipment FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical c
14、ommittees (IEC National Committees). The object of the 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 activities, the IEC publishes International Standards. Their preparation is en
15、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. The IEC collaborates closely with the
16、International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjec
17、ts since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by th
18、e National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresp
19、onding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that
20、some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61000-6-6 has been prepared by subcommittee 77C: High power transient phenomena, of IEC technical c
21、ommittee 77: Electromagnetic compatibility. The text of this standard is based on the following documents: FDIS Report on voting 77C/135/FDIS 77C/138/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 publicati
22、on has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until 2008. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. Page3 BSIEC6100066:2003-00

27、ts high-altitude electromagnetic pulse (HEMP) immunity requirements for electrical and electronic equipment intended for use indoors. The indoor HEMP environment depends on the electromagnetic shielding quality of a facility and the level of protection against the conducted environment. This standar
28、d is intended for all facility types including residential, commercial, light industrial, hospitals, heavy industrial, power substations and power generation facilities. This standard includes indoor equipment intended to be connected to a low-voltage (1 kV or less) power network, to the telecom net
29、work and/or to external antennas. Immunity test values are based on the 90 % severity levels in IEC 61000-4-25. All telecom lines are assumed to have gas-tube protectors at the point where they enter the building and insulation flashover on low-voltage lines are assumed at three times that of lightn
30、ing. For signal ports connected to internal cables, severity test levels are based on cables that have a total length of 10 m and a procedure is provided for longer cables. Large and small indoor equipment are covered by this part of IEC 61000. Small-sized equipment is defined in IEC 61000-4-25 as a
31、n object with cubical dimensions of less than 1 m 1 m 1 m. Examples of small-sized equipment are rack-mounted equipment and desktop personal computers (PCs). Large equipment includes an apparatus with cubical dimensions equal to or greater than 1 m 1 m 1 m. No dedicated IEC product or product-family
32、 immunity standard for HEMP is currently published for indoor equipment. When a relevant dedicated product or product-family immunity standard is developed, it will take precedence over all aspects of this generic standard. It should be noted that the HEMP environment is a very low probability occur
33、rence, and therefore it is not recommended that this generic standard be made mandatory except through agreements between facility owners and equipment manufacturers. This part of IEC 61000 does not specify safety requirements for equipment, such as protection against shock, insulation coordination,
34、 and related dielectric tests. Nevertheless, the immunity tests described in this part of IEC 61000 involve hazardous voltages. High-voltage precautions are necessary to protect the health and safety of test personnel. 2 Normative references The following referenced documents are indispensable for t

40、ironments IEC 61000-6-5, Electromagnetic compatibility (EMC) Part 6-5: Generic standards Immunity for power station and substation environments 3 General For the purpose of this part of IEC 61000, the nuclear high-altitude electromagnetic pulse environment consists of two major parts: a radiated env
41、ironment and a conducted environment. The standard HEMP radiated environment is defined in IEC 61000-2-9 and the conducted environment is defined in IEC 61000-2-10. Both types of environments are classified in IEC 61000-2-11. The conducted environment includes a very intense fast-rising short-durati
42、on surge. This transient is short relative to the standard lightning 1,2/50 s wave. Thus, equipment with immunity to the HEMP conducted environment is not necessarily immune to the standard lightning current waveform. Similarly, lightning protection will not assure protection against HEMP. However,
43、it would be unwise to protect against HEMP and risk susceptibility to lightning. Therefore, lightning protection in the form of SPDs (see 4.13) on power, telecom, and antenna cables at the building entrance is highly recommended. Lightning protection will not provide adequate HEMP protection but it
44、will usually reduce the peak HEMP overvoltages on long lines. Immunity to the 1,2/50 s surge for additional protection against lightning is required by this generic standard. Also, the immunity requirements for industrial environments (IEC 61000-6-2) are used to establish minimal electrical fast tra
45、nsients (EFT) and 1,2/50 s surge test levels to assure immunity to transients in commercial and industrial buildings. If equipment has been qualified for industrial environments to the EFT and 1,2/50 s surge test levels specified in Tables 2 to 7, then such qualification is adequate to meet the requ
46、irements of this standard for those tests.
