Superconducting fault current limiters (SFCL) use the transition of superconducting materials as the mechanism to introduce high impedance in the line to be protected when the current in the line surpasses the fixed maximum value. When the normal wor

Most second-generation high-temperature superconductor tapes are prepared on ferromagnetic substrates. It is known that the presence of this substrate increases the tape's ac losses. Thus, it is important to determine the contribution of the ferromag

In multilayer and magnetically coupled coils made from tape, the loss in each segment of tape in a coil depends on the parallel segments in the adjacent layers. In the case of a single multilayer coil, the current in all the layers is the same, but i
