One of the major challenges facing the electric industry is how to manage network fault levels, the magnitude of the electrical current that flows into a fault or short circuit. These current levels ...

A new theory could help build future superconducting alternating-current fault-current limiters for electricity transmission and distribution systems. The work identifies design strategies that can ...

American Superconductor Corporation and Siemens AG announced commercial-grade performance levels for a medium voltage superconductor surge protection device known as a fault current limiter (FCL). The ...

American Superconductor (AMSC) and China's Institute of Electrical Engineering (IEE) recently announced that IEE has successfully demonstrated a superconductor-based fault current limiter—essentially ...
