Fault current limiters (FCLs) serve as essential protective devices within modern power systems, mitigating the potentially damaging effects of fault currents. By dynamically increasing their ...

Residual current circuit breakers (RCCB) play a narrow but important role in electrical protection. They are frequently specified, often misunderstood, and regularly credited with capabilities they ...

According to the IEEE Buff Book, "A power cable must be protected from overheating due to excessive short-circuit current flowing in its conductor," which may damage or destroy the insulation. It also ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding ...

Testing a circuit breaker is about judging reliability under fault conditions, not just checking continuity or voltage. A ...

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 ...

A friend who was buying an older house was concerned about electrical safety and asked for my opinion as an electrical engineer. All of the AC receptacles (also called outlets) in the house were the ...
