Abstract :
The progress of a European-funded project on the ac losses of Bi-2223 tapes for power applications, co-ordinated by BICC Superconductors, is partially reviewed. Results of loss measurements by four of the partners are presented including: a round-robin of electrical measurements; a consideration of the influence of the E-J characteristic; measurements at frequencies up to 2.5 kHz and a measurement of the losses in a twisted tape due to an applied AC field.
