Superconducting HTS-2G Hybrid Magnetic Mutual Induction System in Liquid Nitrogen

This paper presents two prototypes and experimental results of a superconducting HTS-2G hybrid magnetic mutual induction system in liquid nitrogen. Experimental setup consists of two flat spiral HTS-2G coils submerged in liquid nitrogen. Investigated prototypes are created by using 3D printed liquid nitrogen tanks, coil skeletons, spacers and coil supports. All coils are made of HTS-2G flat wires with liquid nitrogen transition point at Tc=77 K. For each prototype no load and load characteristics are measured. Results for coupling coefficients are obtained for each hybrid inductive system.
