Fault ride-through enhancement of fixed speed wind turbine using bridge-type fault current limiter
Journal of Electrical Systems and Information Technology, 2016 The interaction between wind energy turbines and the grid results in two main problems, increasing the short-circuit level and reducing the Fault Ride-Through (FRT) capability during faults.

Superconducting fault current limiter application in a power-dense marine electrical system [PDF]
, 2011 Power-dense, low-voltage marine electrical systems have the potential for extremely high fault currents. Superconducting fault current limiters (SFCLs) have been of interest for many years and offer an effective method for reducing fault currents.

A practical study of the 66‐kV fault current limiter (FCL) system with rectifier
Electrical Engineering in Japan, 2005 AbstractA fault current limiter (FCL) is extensively expected to suppress fault current, particularly required for a trunk power system's heavily connected high‐voltage transmission lines, such as the 500‐kV‐class power system which constitutes the nucleus of the electric power system.

Investigation of the Operation of Active Superconducting Fault Current Limiters in Distribution Networks Connected to Microgrids [PDF]
Journal of Applied Research in Electrical Engineering, 2023 Increasing the penetration level of distributed generation (DG) units in radial power distribution systems can increase the short-circuit level in these networks, which can, in turn, have destructive effects such as exceeding the tolerable current of the
