    29、ical distribution systems 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 concern

    30、ing 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

    31、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 clo

    32、sely 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 relev

    33、ant 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 t

    34、echnical 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

    35、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 prov

    36、ide 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

    37、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 expense

    38、s 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) Attenti

    39、on 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 61557-13 has been prepared by IEC technical committee TC85: Measuring equi

    40、pment for electrical and electromagnetic quantities. The text of this standard is based on the following documents: FDIS Report on voting 85/387/FDIS 85/391/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. 61557-1

    41、3 IEC:2011 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This part is to be used in conjunction with IEC 61557-1:2007. A list of all parts of the IEC 61557 series, published under the general title Electrical safety in low voltage distribution systems up to 1

    42、 000 V a.c. and 1 500 V d.c. Equipment for testing,measuring or monitoring of protective measures, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.c

    43、h“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 61557-13 IEC:2011 INTRODUCTION During periodical inspections of electrical installations, it is increasingly difficult to carry out measureme

    44、nts of insulation resistances with devices according to IEC 61557-2 when the installations cannot be switched off for long periods and when there are sensitive appliances connected. Therefore, the measurement of leakage currents can provide additional information about the safe or unsafe situation o

    45、f an installation. Furthermore, the user has the opportunity to place current clamps and sensors on different points of the distribution system for troubleshooting nuisance tripping of RCDs, alarms of RCMs and other problems caused by low frequency leakage currents. Unfortunately, the presence of hi

    46、gh external magnetic fields has a big impact on the performance of commonly used current clamps and sensors. High uncertainty and non- repeatability of readings can lead to unsafe interpretations. This standard defines performance classes for current clamps and sensors in relationship to ranges of h

    47、igh external magnetic fields and gives guidance to the user to choose the appropriate measuring device for a given situation. 61557-13 IEC:2011 7 ELECTRICAL SAFETY IN LOW VOLTAGE DISTRIBUTION SYSTEMS UP TO 1 000 V a.c.
