19、1:2008 +A2:2009 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ELECTROMAGNETIC COMPATIBILITY (EMC) Part 3-2: Limits Limits for harmonic current emissions (equipment input current 16 A per phase) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardizat
20、ion 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 activities, IEC publishes Internatio
21、nal 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 subject dealt with may participate in t
22、his 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 determined by agreement between the tw
23、o 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 Committees. 3) IEC Publications have th
24、e 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 which they are used or for any misinter
25、pretation 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 Publication and the corresponding national
26、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 Publication. 6) All users should ensure that they have the latest edition of t
27、his 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, property damage or other damage of any nature whatsoever, whether direct or i
28、ndirect, 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 this publication. Use of the referenced publications is indispensable for
29、 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 or all such patent rights. International Standard IEC 61000-3-2 has been
30、 prepared by sub-committee 77A: Low-frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility. This consolidated version of IEC 61000-3-2 consists of the third edition (2005) documents 77A/503/FDIS and 77A/516/RVD, its amendment 1 (2008) documents 77A/625/FDIS and 77A/641/RVD
31、 and its amendment 2 (2009) documents 77A/674/FDIS and 77A/677/RVD. The technical content is therefore identical to the base edition and its amendments and has been prepared for user convenience. It bears the edition number 3.2. A vertical line in the margin shows where the base publication has been
32、 modified by amendments 1 and 2.

The committee has d
33、ecided that the contents of the base publication and its amendments 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, repla
34、ced by a revised edition, or amended.

37、ns which are to be published either as international standards, technical specifications, or as technical reports. These standards and reports will be published in chronological order and numbered accordingly (for example, 61000-6-1). This part is an international standard which gives emission limit
38、s for harmonic currents from equipment having an input current up to and including 16 A per phase. This part is a Product Family Standard.

39、9 ELECTROMAGNETIC COMPATIBILITY (EMC) Part 3-2: Limits Limits for harmonic current emissions (equipment input current 16 A per phase) 1 Scope This part of IEC 61000 deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of th
40、e input current which may be produced by equipment tested under specified conditions. Harmonic components are measured according to Annexes A and B. This part of IEC 61000 is applicable to electrical and electronic equipment having an input current up to and including 16 A per phase, and intended to
41、 be connected to public low-voltage distribution systems. Arc welding equipment which is not professional equipment, with input current up to and including 16 A per phase, is included in this standard. Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded from
42、 this standard and may be subject to installation restrictions as indicated in IEC 61000-3-4 or IEC 61000-3-12. The tests according to this standard are type tests. Test conditions for particular equipment are given in Annex C. For systems with nominal voltages less than 220 V (line-to-neutral), the
43、 limits have not yet been considered. NOTE The words apparatus, appliance, device and equipment are used throughout this standard. They have the same meaning for the purpose of this standard. 2 Normative references The following referenced documents are indispensable for the application of this docu
44、ment. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
