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 ...

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 ...

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 ...

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 ...

What distinguishes a medium voltage circuit breaker from other types is not the enclosure or operating mechanism, but the method of arc extinction. The interruption medium governs arc energy, ...

Researchers from Colombia’s Metropolitan Technological Institute of Medellin (ITM) have aggregated an open dataset of PV performance under different fault conditions. Available online, the set ...

Recently, frequent Design Idea (DI) author Christopher Paul showcased an innovative and high performance true-two-wire current source using a depletion mode MOSFET as the pass device in “A precision, ...

Electricity does not choose “the path of least resistance,” but flows on all paths presented to it. The flow divides among those paths in inverse proportion to their impedances (those paths with lower ...

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 ...
