标准摘要
[中文适用范围]： 本部分 IEC 61557 定义了用于在高达 1000 V 交流电和 1500 V 直流电的电气配电系统中测量漏电流的手持式和手持操作式电流钳和传感器的特殊性能要求，同时考虑了高外部低频磁场和其他影响量的影响。除非制造商另有规定，本标准不适用于与根据 IEC 61557-9 的绝缘故障定位设备配合使用的电流钳或传感器。 [外文原描述]： IEC 61557-13:2011 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 a.c. and 1 500 V d.c., taking into account the influence of high external low-frequency magnetic fields and other influencing quantities. This standard does not apply to current clamps or sensors which are used in combination with devices for insulation fault location according to IEC 61557-9, unless it is specified by the manufacturer.
