Superconducting Fault Current Limiter.
TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1997 There is disclosed a current limiter having a plurality of current limiting units provided for electric paths constituting a plurality of phases, Each current limiting unit is constituted by a superconducting coil functioning as a first current limiting element formed in a non-inductive winding manner by connecting two superconducting coils in series ...

Modelling of Resistive Type Superconducting Fault Current Limiter for HVDC Grids
Energies, 2022 The protection of high voltage direct current (HVDC) grids is a challenge considering that the protection system must detect, locate, and interrupt large fault currents in a few milliseconds. Resistive type superconducting fault current limiters (R-SFCL)

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 ...

A New Type of DC Superconducting Fault Current Limiter [PDF]
IEEE Transactions on Applied Superconductivity, 2019 A new type of Superconducting Fault Current Limiter (SFCL) for dc applications is proposed. This SFCL consists of a current transmission/limiting coil, an iron-core, and a set of superconductor rings. The superconductor rings are placed between the current transmission/limiting coil and the iron-core.
