| Abstract |
Superconducting tape is being developed for electrical equipment such as superconducting transformers and generators etc. AC loss reduction is primary concerned in the development of such high-efficiency equipment. AC losses in Bi-2223 silver-sheathed tapes, both single and multi-filamentary, were investigated by means of AC magnetization techniques when longitudinal fields are applied. The experiment resultswere compared with the hysteresis loss equation based on Bean model and the eddy current loss equation. The AC loss of the mono-filamentary tape was dominated by the hysteresis. On the contrary, the AC loss of the multi-filamentary tape was substantially dominated by the eddy current loss in the silver matrix. |
