초록
Applying the AC over-currents over the critical current to Bi-2223/Ag tape having 56 A Ie, resistance increase with the duration of current application was measured and analyzed. In addition, the influence of the tape's electrical insulation on the over-current characteristics was investigated and compared with each other. From the results, we will establish the safe operating condition against the AC over-currents and the protection of the tape for the practical power application such as cable and transformer.
