We have developed a calorimeter with a sensitivity of better than 1 mW/m for measuring AC losses in HTS multi-strand conductors for superconducting power transmission lines over a temperature range of 64 K to 80 K. By choosing a temperature difference technique we eliminate the need for corrections
It is shown that the observed ac loss in a cylindrical (Bi,\_xPbx)2Sr2Ca2Cu.~Oy (Bi-2223) bulk superconductor with the diameter of 9.6mm in the ac magnetic field depends on the frequency of ac field contradicting the conventional theory based on the critical state model. The numerical simulation of
