Abstract

The influence of the sample length, the transverse resistance between Ag matrix and HTS elements as well as position of potential taps and leads on DC and AC voltage-current characteristics and on the measurement of J_c and AC losses in Ag sheathed HTS tapes was studied. Experimental results on these parameters obtained on a two concentric layer Ag/Bi-2223 tape are presented and compared with theory. Conclusions concerning the correct measurements of these parameters are formulated
