62 FOREWORD

63 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

64 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

65 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

66 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

67 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

68 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

69 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

70 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

71 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

72 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

73 consensus of opinion on the relevant subjects since each technical committee has representation from all

74 interested IEC National Committees.

75 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

76 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

77 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

78 misinterpretation by any end user.

79 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

80 transparently to the maximum extent possible in their national and regional publications. Any divergence between

81 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

82 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

83 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

84 services carried out by independent certification bodies.

85 6) All users should ensure that they have the latest edition of this publication.

86 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

87 members of its technical committees and IEC National Committees for any personal injury, property damage or

88 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

89 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

90 Publications.

91 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

92 indispensable for the correct application of this publication.

93 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

94 rights. IEC shall not be held responsible for identifying any or all such patent rights.

95 International Standard IEC 61557-13 has been prepared by IEC technical committee 85:

96 Measuring equipment for electrical and electromagnetic quantities

97 This second edition cancels and replaces the first edition published in 2011. This edition

98 constitutes a technical revision.

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

100 edition:
101 a) The term “fixing device” has been removed

102 b) The measuring range was changed to a display range, the indication of DC or peak

103 values was added in 4.1.

104 c) The frequency for the test of sensitivity for low-frequency magnetic was defined in 4.2;

105 d) The specified measuring range is now defined as the range of indicated values based

106 on the operating uncertainty in 4.3.
107 e) Alignment of the structure with that of the whole IEC 61557 series ;

130 INTRODUCTION

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

132 measurements of insulation resistances with devices in accordance with IEC 61557-2 when the

133 installations cannot be switched off for long periods and when there are sensitive appliances

134 connected. Therefore, the measurement of leakage currents can provide additional information

135 about the safe or unsafe situation of an installation.

136 Furthermore, the user has the opportunity to place current clamps and sensors on different

137 points of the distribution system for troubleshooting nuisance tripping of RCDs, alarms of RCMs

138 and other problems caused by low-frequency leakage currents.

139 Unfortunately, the presence of high external magnetic fields has a big impact on the

140 performance of commonly used current clamps and sensors. High uncertainty and non-

141 repeatability of readings can lead to unsafe interpretations.

142 This standard defines performance classes for current clamps and sensors in relationship to

143 ranges of high external magnetic fields and gives guidance to the user to choose the appropriate

144 measuring device for a given situation.

145 The hand-held and hand-manipulated current clamps and sensors can be stand-alone

146 instruments or accessories of instruments.
