Abstract
Self magnetic field in a Bus bar usually degrades the critical current in it. Actually the total critical current of a Bus bar is not the same as the sum of total critical current of each stacked HTS tape. This is due to the self field effects in a bus bar. To reduce the degradations of critical current in a bus bar, we need to analyze the self field distributions in a bus bar. Conceptually, by rearranging the each stacked tapes, the self field effects can be minimized. In this paper, we calculate the self magnetic field distributions across a bus bar analytically, with the variations of the relative angle of the two conductors in a go-and-return pair. As a result, we suggest that the optimum relative angle exist which minimize the self field effect in a bus bar.
