The thesis topic concerns the limitation of fault current high temperature superconducting (HTS), reported in scientific literature by the acronym HTSFCL (High Temperature Superconducting Fault Current Limiter) or more commonly with SFCL. These devices, at least in their ideal concept, turn on limiting short-circuit current only when the event of failure occurs, and are transparent to the network during normal operating conditions. The thesis is therefore focused on the study of diff�erent types of SFCL and results in the production of a new and original concept of superconducting limiter, called "DC Resistive SFCL". It has designed and patented in the Department of Electrical Engineering University of Bologna. The author and ing. Antonio Morandi (tutor) are the inventors. The objective of the thesis is therefore to propose a type of SFCL which may have the potential to be a viable economic solution as well as technique. The innovative concept of DC Resistive SFCL device, in fact, provides a DC operating conditions for the used superconducting (SC). It allows the use of cryogen-free solutions for cooling system and the exploitation of cheap SC materials (MgB2), both of reality are already commercially existing and indeed precluded by the types of SFCL which provides an AC operating conditions for the used SC material.
