摘要
Abstract
The study of the coupling characteristics of shielded cable in an EM pulse radiation field beth for EMI control and EMP protection on electrical equipment and systems becomes absolutely essential. A double-transmission-line model of shielded cable was therefore investigated. The coupling current response on the shield layer and inner conductor of two typical shielded cables in different grounding states and range of frequency of EMP field were calculated. The coupling current on the inner-conductor of braid shielded cable is typically very higher in several orders than of a tubular shielded cable. The coupling current on the inner-conductor decreases along with the increase of frequency for the tubular shielded cable due to the skin effect, but increases for braid shielded cable as result of the effect of braid inductance and eyelet inductance.关键词
