Experimental validation of circuit models for bulk current injection (BCI) test on shielded coaxial cables

Abstract

In order to validate, by means of measurement, some existing equivalent circuit models for the bulk current injection (BCI) test, a procedure is proposed to develop a proper circuit model for the injection clamp and the obtained circuit is introduced into the global one representing the overall cable. A suitable experimental set-up has been built and used. The measured induced voltages at the terminations of shielded coaxial cables are compared with those computed by the equivalent circuit. Upper and lower bounds are quantified in order to assess the order of accuracy of the predicted results.
