Including Experimental Aging of Shielded Cables into Bulk Current Injection Simulations

Transfer impedance of shielded cables is a main characteristic to describe cable shielding performance at least up to 1 GHz. Traditionally, a cable shield consists of a braid, a foil, or a combination of them. Braids have attracted a significant amount of research interest, while foils have not. Published studies have concentrated on cable shielding performance when cables are new. In this paper, a highly accelerated aging method for shielded cables is presented and applied to a cable made up of a combination of a braid and foil shield. Finally, the effect of aging on system performance during bulk current injection (BCI) tests is assessed by circuit simulation.
