  Short sample HTS power cable composed of multiple 344C-2G strands and
designed to energize a fast-cycling dipole magnet was exposed to a sweeping
magnetic field in the (2-20) T/s rate. The B-field orientation toward the HTS
strands wide surface was varied from 0 deg. to 10 deg., in steps of 1 deg.. The
test arrangement allowed measurement of the combined hysteresis and eddy
current power losses. For the validity of these measurements, the power losses
of a short sample cable composed of multiple LTS wire strands were also
performed to compare with the known data. The test arrangement of the power
cable is described, and the test results are compared with the projections for
the eddy and hysteresis power losses using the fine details of the test cable
structures.
