Superconducting Fault Current Limiter

open access: yes, 2018
The superconducting fault current limiter concept explains two types of superconducting materials firstly resistive SFCL, Secondly, Inductive-SFCL. We also study some applications of SFCLs which is used to limit the fault - current that occurs in power system.
