Abstract

For the application of HTS wire to AC power equipment, a conductor with high current capacity and low loss is required. CORC®, one of the high-current conductors manufactured using several HTS wires, is made by winding the wires in a spiral on a cylindrical former. Because the magnetization loss of a CORC® conductor depends on the degree of magnetic coupling between the wires constituting the CORC®, it is necessary to know the value of the magnetization loss of the CORC® itself. In order to obtain an accurate loss value, it is necessary to know the effect of the ratio of the winding pitch of the CORC® conductor in the pickup coil region sampling the magnetization loss signal. To confirm this effect, we prepare CORC® samples having various winding pitches, and measure and compare the magnetization losses. In addition, the magnetization loss was measured while rotating the CORC® samples and it was examined whether there was a difference in the magnetization loss according to the rotation.
