标准摘要
[中文适用范围]： 本部分 IEC 62153 通过向电缆屏蔽层施加明确定义的电流和电压并测量感应电压来确定表面转移阻抗，从而确定电缆屏蔽的屏蔽效果。该测试仅测量转移阻抗的磁分量。 注：静电分量（电容耦合阻抗）的测量在 IEC 62153-4-8 中描述。 三轴测量方法通常适用于频率范围：1 米样品长度可达 30 MHz，0.3 米样品长度可达 100 MHz，这对应于样品中波长的大约 1/6 的电长度。 [外文原描述]： IEC 62153-4-3:2013+AMD1:2024 CSV determines the screening effectiveness of a cable shield by applying a well-defined current and voltage to the screen of the cable and measuring the induced voltage in order to determine the surface transfer impedance. This test measures only the magnetic component of the transfer impedance. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - now three different test configurations are described; - formulas to calculate the maximum frequency up to which the different test configurations can be used are included; - the effect of ground loops is described.
