The Method of Voltage Calculation on Inner Wire of Shielded Cable Based on Transfer Function

Abstract

As well known for voltage calculation on the inner wires of shielded cables the transfer impedance is used. The transfer impedance relates a current on the external surface of a shield to the voltage on the inner wire. Similarly, to determine shielding efficiency of cable it is possible to use transfer function. This paper describes computational procedure for voltages calculation on inner wires of shielded cables generated from pulse currents or potentials on structural elements of technical units. The procedure base on approximation of experimental data of frequency response of transfer function
