Current–Time Characteristics of Resistive Superconducting Fault Current Limiters [PDF]
IEEE Transactions on Applied Superconductivity, 2012 Superconducting fault current limiters (SFCLs) may play an important role in power-dense electrical systems. Therefore, it is important to understand the dynamic characteristics of SFCLs. This will allow the behavior of multiple SFCLs in a system to be fully understood during faults and other transient conditions, which will consequently permit the ...
