摘要

屏蔽多导体电缆的复杂传输阻抗和传输导纳的确定是计算电缆内芯扰动电流的前提。采用基于改进的三轴测量装置的测量程序，使用多导体传输线理论进行评估，可以确定屏蔽多导体电缆的每个内导体在宽频率范围内的单个传输阻抗和导纳。本文给出了通过测量传递阻抗和导纳来确定屏蔽不均匀点的位置和计算屏蔽不均匀点面积的方法。

Characterization of shield inhomogeneities of multiconductor cables by evaluation of measured transfer impedances and admittances

The determination of the complex transfer impedances and transfer admittances of shielded multiconductor cables is the prerequisite for calculating disturbing currents on the inner wires of the cable. With a measurement procedure based on the improved triaxial measurement setups using multiconductor transmission line theory for evaluation, it is possible to determine individual transfer impedances and admittances for each inner conductor of a shielded multiconductor cable over a broad frequency range. This paper shows the determination of the location and the calculation of the area of shield inhomogeneities by the evaluation of measured transfer impedances and admittances.
