Safety of transformers, reactors, power supply units and combinations thereof - EMC requirements

IEC 62041:2010 applies to transformers, reactors, power supply units and combinations thereof covered by the IEC 61558 series of standards. This standard deals with the electromagnetic compatibility requirements for emission and immunity within the frequency range 0 Hz - 400 GHz. No measurement needs to be performed at frequencies where no requirement is specified. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the frequency range for tests according to IEC 61000-4-3 has been extended above 1 GHz according to technologies used in this frequency area; - the testing requirements according to IEC 61000-4-11 have been amended significantly; - the inclusion of a clause on tests in series production; - the inclusion of a new clause on measurement uncertainly, and - the inclusion of requirements on DC power ports and telecommunication ports. It has the status of a product family EMC standard in accordance with IEC Guide 107:2009, Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. In the meantime, the previous edition can still be ordered by contacting your local IEC member National Committee or the IEC Central Office.

La présente norme traite des exigences de compatibilité électromagnétique pour l'émission et l'immunité dans la bande de fréquences 0 Hz - 400 GHz. Aucune mesure n'est nécessaire aux fréquences pour lesquelles aucune exigence n'est spécifiée. Cette deuxième édition annule et remplace la première édition parue en 2003. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - la plage de fréquences pour les essais selon la CEI 61000-4-3 a été étendue à des fréquences au-dessus de 1 GHz d'après les technologies utilisées dans cette zone de fréquence; - les exigences d'essai d'après la CEI 61000-4-11 ont été amendées de manière significative; - ajout d'un article sur les essais de production en série; - ajout d'un nouvel article sur l'incertitude des mesures, et - l'introduction d'exigences sur les accès de puissance en courant continu et sur les accès de télécommunication. Elle a le statut d'une norme CEM de famille de produits conformément au Guide CEI 107:2009, Compatibilité électromagnétique - Guide pour la rédaction des publications sur la compatibilité électromagnétique. L'attention des Comités Nationaux est attirée sur le fait que les fabricants d'appareils et les organismes d'essai peuvent avoir besoin d'une période transitoire après la publication d'une nouvelle publication CEI, ou d'une publication amendée ou révisée, pour fabriquer des produits conformes aux nouvelles exigences et pour adapter leurs équipements aux nouveaux essais ou aux essais révisés. Le comité recommande que le contenu de cette publication soit entériné au niveau national non plus tôt que 12 mois de la date de publication. Pendant ce temps, l'édition précédente peut toujours être commandée auprès du Comité National CEI de votre pays ou auprès du bureau Central de la CEI.

Varnost močnostnih transformatorjev, dušilk, napajalnikov in kombinacij teh elementov - Zahteve EMC (IEC 62041:2010)

Ta mednarodni standard za družino izdelkov velja za transformatorje, dušilke, napajalnike in kombinacije teh elementov, zajetih v skupini standardov IEC 61558. Ta standard obravnava zahteve za elektromagnetno združljivost za oddajanje in odpornost v frekvenčnem razponu od 0 Hz do 400 GHz. Kjer zahteve niso določene, ni potrebno nobeno merjenje. Transformatorji, dušilke, napajalniki in kombinacije teh elementov, dobavljeni z napravo ali opremo ali v njiju vgrajeni, morajo upoštevati ustrezne standarde o elektromagnetni združljivosti, ki veljajo za te naprave ali opremo. Vendar se ta standard lahko uporabi tudi kot vodilo za ločeno preskušanje transformatorjev, dušilk, napajalnikov in kombinacij teh elementov, preden se vgradijo v napravo ali opremo. Ta standard o elektromagnetni združljivosti zajema le delovanje. Druge operacije transformatorjev, dušilk in napajalnikov (npr. simulacija okvar v električnem vezju za namene preskušanja ali funkcionalne varnosti zaradi učinkov elektromagnetnih pojavov ali ocenjevanja človeka pri izpostavljenosti elektromagnetnim poljem (EMF), niso obravnavane v tem standardu. Ta standard ne velja za: - brezprekinitvene napajalnike (UPS), zajete v skupini IEC 62040; napajalnike, zajete v IEC 61204-3 (tj. pretvornike DC-DC, opremo za napajanje z enosmernim tokom in njegovo distribucijo ter napajalnike za uporabo v napravah, zajetih v IEC 60950-1, IEC 61010-1, IEC 60601-1, IEC 60065 in IEC 62368-1); napajalnike in pretvornike za uporabo v izdelkih, zajetih v IEC 61347-1.

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 standardization 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 entrusted 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 International 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 since 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 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 in 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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is 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 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 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 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 shall not be held responsible for identifying any or all such patent rights.

International standard IEC 62041 has been prepared by Technical Committee 96: Transformers,

reactors, power supply units and combinations thereof.

This second edition cancels and replaces the first edition published in 2003. It constitutes a

technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

– the frequency range for tests according to IEC 61000-4-3 has been extended above 1 GHz

according to technologies used in this frequency area;

– the testing requirements according to IEC 61000-4-11 have been amended significantly;

– the inclusion of a clause on tests in series production;
– the inclusion of a new clause on measurement uncertainly, and

EMC REQUIREMENTS
1 Scope

This international product family standard applies to transformers, reactors, power supply

units and combinations thereof covered by the IEC 61558 series of standards. This standard

deals with the electromagnetic compatibility requirements for emission and immunity within the

frequency range 0 Hz - 400 GHz. No measurement needs to be performed at frequencies

where no requirement is specified.

Transformers, reactors, power supply units and combinations thereof delivered with or

incorporated in an appliance or equipment should follow the relevant EMC standard applicable

to that appliance or equipment. However, this standard may be used as a guide to test the

transformers, reactors, power supply units and combinations thereof separately before

incorporating them in the appliance or equipment.

This EMC standard covers performance only. Other operations of the transformers, reactors

and power supply units (e.g. simulated faults in the electric circuitry for testing purposes or

functional safety due to the effects of the electromagnetic phenomena, or evaluation of human

being for exposure to electromagnetic fields (EMF)) have not been taken into consideration in

this standard.

NOTE When EUT (Equipment under Test) is used, it covers transformers, reactors, power supply units and

combinations thereof where applicable.
This standard does not apply to:
– uninterruptible power supplies (UPS) covered by IEC 62040 series;
– power supply units covered by IEC 61204-3,

(i.e. DC-DC converters, DC power and distribution equipment and power supply units for

use in applications covered by IEC 60950-1, IEC 61010-1, IEC 60601-1, IEC 60065 and IEC

62368-1);

– power supplies and converters for use with or in products covered by IEC 61347-1.
