IEC 62153-4-3:20 13+AMD1:2024 CSV通过向电缆的屏蔽施加明确定义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电缆屏蔽的屏蔽有效性。该测试仅测量传输阻抗的磁性分量。这第二版取消并取代了2006年出版的第一版。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: -现在描述三种不同的测试配置； -包括计算可使用不同测试配置的最大频率的公式； -描述了接地回路的影响。

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.
