| Popis: | The relevance of the transfer admittance in the coupling process of external electromagnetic fields into shielded cables is discussed. Methods for including the transfer impedance into EMC analysis are well-developed. But, there is still uncertainty, under which circumstances the transfer admittance becomes the more important characteristic cable parameter, that eventually determines the induced voltages and currents within the cable. Starting from the underlying concept of this study, analytical expressions for the induced voltages at the internal loads of the cable are derived. Finally, the contribution of both coupling parameters, the transfer admittance and the transfer impedance, is evaluated in an example. |
