SYSTEMS HAVING A RATED VOLTAGE UP TO AND INCLUDING 1 000 V Part 1: General Performance, testing and rating Safety requirements Guide for installation and operation FOREWORD 1) The International Electrotechnical

27、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

28、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 Commit

29、tee 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 acc

30、ordance 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 i

31、nterested 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 resp

32、onsible 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 divergen

33、ce 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 mark

34、s 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

35、 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 Publ

36、ication 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 Publ

37、ication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. DISCLAIMER This Redline version is not an official IEC Standard and is intended only to provide the user with an indication of what changes have been made to the previous ver

38、sion. Only the current version of the standard is to be considered the official document. This Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. A vertical bar appears in the margin wherever a change has been made. Addit

39、ions and deletions are displayed in red, with deletions being struck through. 6 IEC 60831-1:2014 RLV IEC 2014 International Standard IEC 60831-1 has been prepared by IEC technical committee 33: Power capacitors and their applications. This third edition cancels and replaces the second edition publis

40、hed in 1996 and Amendment 1:2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Updating of the normative references; b) Test conditions have been clarified; c) Thermal stability test has been

41、 clarified; d) Maximum permissible voltage and current have been clarified; e) The protection of the environment has been amended with safety concerns and plastic quality requirements. The text of this standard is based on the following documents: FDIS Report on voting 33/543/FDIS 33/550/RVD Full in

42、formation on the voting for the approval of this standard can be found in the report on voting indicated in the above table.
