A Nitrogen Gas Cooled, Hybrid, High Temperature Superconducting Fault Current Limiter.

Investigates the electrical and thermodynamic requirements to be fulfilled by a high temperature superconductor if the fault current limiter (FCL) is of a hybrid type. Concept of the hybrid resistive-type superconducting FCL; Basis of the concept; Critical current density; Feasibility of superconductor cooling by gaseous nitrogen.
