| Abstract: | In this paper,shielding efficiency of cable is definded as decibel of ratio between skin current and core-current p-p value.The measuring method of current injection is introduced for the shielding efficiency of multi-wire cable.The internal resistance of equivalent voltage source and shielding efficiency are obtained for the cable of a hundred wires.The measuring results of total shielding effect for first sample cable with a hundred wires in external field testing are calculated and discussed. |
