A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems
Energy Science &Engineering, EarlyView.This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...
