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 ...

Design Approaches for Oxygen Reduction Systems for Warehouse Storage Applications
Fire and Materials, EarlyView.ABSTRACT Oxygen reduction systems (ORS) are protection systems, with a design protection objective to limit fire spread beyond the point of ignition. Research has shown that the prescriptive design methods, in VdS 3527, EN 16750, and ISO 20338, are not appropriate as prescriptive design methods as they result in insufficient protection levels.
