Experimental Study of Magnetization Loss by External Magnetic Field in CORC-TSTC Hybrid Composite Conductor

Several different types of superconducting cable have been investigated for large currents in the tens to hundreds of kA class, consisting of several high-temperature superconducting wires stacked together. They all are designed for large magnets excited by direct current, and all have transposed or twisted shapes for uniformity of current distribution among the stacked strands. In this study, a CORC-TSTC hybrid conductor is presented for application in high-capacity AC power equipment. Fabrication of samples and measurement of magnetization loss were carried out, followed by an analysis of loss patterns through comparison of results. The study demonstrates a promising application potential for the proposed hybrid conductor.
