IEC 62153-4-7:20 15(E)描述了一种三轴方法，其适于确定配合的屏蔽连接器(包括电缆和连接器之间的连接)和电缆组件的表面传递阻抗和/或屏蔽衰减和耦合衰减。该方法还可以扩展到确定平衡或多针连接器和多芯电缆组件的传输阻抗、耦合或屏蔽衰减。对于传输阻抗和屏蔽或耦合衰减的测量，只需要一个测试装置。与上一版相比，此版本包括以下重大技术变更:该文件被修订和更新。包括修订后的IEC 62153-4-3:20 13和IEC 62153-4-4:20 15的变更。现在可以在发电机现场实现失配的测量，不需要阻抗匹配设备。
IEC 62153-4-7:2015(E) describes a triaxial method, suitable to determine the surface transfer impedance and/or screening attenuation and coupling attenuation of mated screened connectors (including the connection between cable and connector) and cable assemblies. This method could also be extended to determine the transfer impedance, coupling or screening attenuation of balanced or multipin connectors and multicore cable assemblies. For the measurement of transfer impedance and screening- or coupling attenuation, only one test set-up is needed. This edition includes the following significant technical changes with respect to the previous edition:
The document is revised and updated. The changes of the revised IEC 62153-4-3:2013, and IEC 62153-4-4:2015, are included. Measurements can be achieved now with mismatch at the generator site, impedance matching devices are not necessary.
