标准摘要
[中文适用范围]： 该测试通过向电缆屏蔽施加明确的电流和电压并测量感应电压以确定表面传输阻抗来确定屏蔽电缆的屏蔽有效性。该测试仅测量传输阻抗的磁性分量。注：测量静电分量（电容耦合阻抗）应采用IEC 62153-4-82中描述的方法。三轴测量方法适用于 1 m 样品长度高达 30 MHz 的频率范围，以及 0,3 m 样品长度高达 100 MHz 的频率范围，这对应于小于样品波长 1/6 的电长度。 [外文原描述]： determines the screening effectiveness of a shielded cable 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.
