Superconducting fault current limiter application in a power-dense marine electrical system [PDF]
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.

Using Matlab/Simulink Software Package to Investigate Fault Behaviors in HVDC System
Existing studies show that several performance issues will arise in the HVDC link during the three phase-to-ground fault at the side of the inverter and that the DC voltage will oscillate around zero and will not affect the rectifier of the AC system ...

An equivalent circuit for the evaluation of cross-country fault currents in medium voltage (MV) distribution networks [PDF]
A Cross-Country Fault (CCF) is the simultaneous occurrence of a couple of Line-to-Ground Faults (LGFs), affecting different phases of same feeder or of two distinct ones, at different fault locations.
