Abstract :
The AC losses of (Bi,Pb)SrCaCuO tapes and wires and a YBaCuO tape have been measured in self and applied fields. The transport losses of the YBCO tape are much higher than any predictions using the critical state model. In this situation, the Bi-2223 wires and twisted tapes have the lowest losses. In applied perpendicular fields the losses of all conductors are currently too high and should be reduced. The Bi-2223 wires are the most flexible and provide the greatest scope for further loss reduction in the short to medium term
