Electrical AC loss measurements of Bi-2223 tapes, performed under the Brite EuRam Research programme SACPA

A series of electrical AC loss measurements on Bi-2223 tapes have been performed under the Brite Euram project SACPA. This included, for the first time, a round-robin of independent self-field AC loss measurements between four laboratories. The very close agreement of data demonstrates the validity of the electrical technique and lays the basis for a measurement standard. Other preliminary measurements in SACPA showing the variation of losses with frequency, temperature and applied DC field are also reported. (C) 1998 Elsevier Science B.V. All rights reserved.
