摘要：

In practical electrical power apparatuses, high Tc superconducting tapes must carry their transport current in the external magnetic field with various directions. The direction of the transverse magnetic field was varied to study the total AC loss characteristics of a twisted and non-twisted BSCCO tape carrying the AC transport current in the AC magnetic field. In non-twisted tapes, the magnetization loss dominates the total AC loss mostly. In twisted tapes, the magnetization loss dominates the total AC loss at large field angle that is the angle between the magnetic field and the tape wide-face, but its contribution to the total AC loss decreases with decreasing field angle. Therefore, in small field angle regime, the total AC can be reduced by twisting. For the total AC loss reduction in the transverse magnetic field with large field angle, increase in the transverse resistivity is required essentially.
