IEC 61557-13:20 23定义了手持式和手动电流钳和传感器的特殊性能要求，用于测量高达1 000 V AC和1 500 V DC的配电系统中的泄漏电流，同时考虑到高外部低频的影响磁场和其他影响量。测量应用示例见附录A。 除非制造商另有规定，否则本文件不适用于与符合IEC 61557-9的绝缘故障定位装置结合使用的电流钳或传感器。 IEC 61557-13:20 23取消并取代了2011年发布的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更:a)术语“固定装置”已被删除； b)测量范围更改为显示范围，在4.1中增加了DC或峰值的指示； c)低频磁场灵敏度测试的频率已在4.2中定义； d)规定的测量范围现在定义为基于4.3中操作不确定度的指示值范围； e)结构与整个IEC 61557系列的结构对齐； f)变型E12(最大负载电流)可以根据制造商的规范来指定。

IEC 61557-13:2023 defines special performance requirements for hand-held and hand manipulated current clamps and sensors for measurement of leakage currents in electrical distribution systems up to 1 000 V AC and 1 500 V DC taking into account the influence of high external low-frequency magnetic fields and other influencing quantities. See Annex A for examples of measurement applications.
This document does not apply to current clamps or sensors that are used in combination with devices for insulation fault location in accordance with IEC 61557-9, unless it is specified by the manufacturer.
IEC 61557-13:2023 cancels and replaces the first edition published in 2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the term "fixing device" has been removed;
b) the measuring range was changed to a display range, the indication of DC or peak values has been added in 4.1;
c) the frequency for the test of sensitivity for low-frequency magnetic fields has been defined in 4.2;
d) the specified measuring range is now defined as the range of indicated values based on the operating uncertainty in 4.3;
e) alignment of the structure with that of the whole IEC 61557 series;
f) the variation E12 (maximum load current), may be specified according to the manufacturer’s specification.
