Influence of Wire Misalignment in Current Injection Probe on the Bulk Current Injection (BCI) Test

In this paper, the wire misalignment inside the current injection probe during BCI testing is analyzed. It is critically examined whether a wire misalignment has a significant impact on the total measurement uncertainty and the reproducibility of the BCI test. For this analysis, a special fixation for a cable wire inside the current injection probe was developed to evaluate different positions of wire misalignment. After measuring the 13 different misalignment positions of the wire, the measured data are compared and evaluated. The main purpose of this analysis is then to decide if the misalignment has a significant impact on the BCI test.
