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.

INTRODUCTION

During periodical inspections of electrical installations, it is increasingly difficult to carry out

measurements 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 of 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 curre

35 FOREWORD 36 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising 37 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote 38 international co-operation on all questions concerning standardization in the electrical and electronic fields. To 39 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, 40 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC 41 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested 42 in the subject dealt with may participate in this preparatory work. International, governmental and non-43 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely 44 with the International Organization for Standardization (ISO) in accordance with conditions determined by 45 agreement between the two organizations. 46 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international 47 consensus of opinion on the relevant subjects since each technical committee has representation from all 48 interested IEC National Committees.

49 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National 50 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC 51 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any 52 misinterpretation by any end user. 53 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications 54 transparently to the maximum extent possible in their national and regional publications. Any divergence 55 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in 56 the latter. 57 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any 58 equipment declared to be in conformity with an IEC Publication. 59 6) All users should ensure that they have the latest edition of this publication. 60 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and 61 members of its technical committees and IEC National Committees for any personal injury, property damage or 62 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and 63 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC 64 Publications.

65 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is 66 indispensable for the correct application of this publication. 67 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of 68 patent rights. IEC shall not be held responsible for identifying any or all such patent rights. 69 International Standard IEC 61557-13 has been prepared by Technical committee 85: 70 Measuring equipment for electrical and electromagnetic quantities. 71 The text of this standard is based on the following documents: 72 CD CC 85/342/CD 85/351/CC

5INTRODUCTION 84 During periodical inspections of electrical installations, it is increasingly difficult to carry out 85 measurements of insulation resistances with devices according to IEC 61557-2 when the 86 installations cannot be switched off for long periods and when there are sensitive appliances 87 connected. Therefore, the measurement of leakage currents can provide additional 88 information about the safe or unsafe situation of an installation. 89 Furthermore, the user has the opportunity to place current clamps and sensors on different 90 points of the distribution system for troubleshooting nuisance tripping of RCDs, alarms of 91 RCMs and other problems caused by low frequency leakage currents. 92 Unfortunately, the presence of high external magnetic fields has a big impact on the 93 performance of commonly used current clamps and sensors. High uncertainty and non- 94 repeatability of readings can lead to unsafe interpretations. 95 This standard defines performance classes for current clamps and sensors in relationship to 96 ranges of high external magnetic fields and gives guidance to the user to choose the 97 appropriate measuring device for a given situation. 98 oSIST FprEN 61557-13:2009
