Abstract
AC applications are projected to be a significant market for HTS condu ctor. The ac magnetic fields perpendicular to the wide face of Bi-2223 conductor (or parallel to the crystallographic c-axis of the oxide su perconductor) are responsible for a significant portion of the total l oss in ac coils. ASC has developed a calorimetric apparatus which can measure long lengths of conductor in a uniform continuous perpendicula r field. This apparatus provides accurate measurement of interfilament or interstrand coupling losses. Calorimetric measurements from long l engths of twisted multifilamentary conductor are presented.
