A single-phase line-to-ground fault simulation with overcurrent relay logic (IEEE 50) and breaker response modeled in PSCAD (2025) ...

Abstract: Users of protective relays apply these devices specific to their needs and applications. In order to perform this task, schemes are developed and applied to protective relays in the form of ...

EIGHTY years ago, Jevons, then professor of logic at Owens College (now the University of Manchester), built a machine which could perform logical inference by mechanical means 1. Other similar ...

There are a few words in the electrical engineering lexicon that will perk any hardware hacker’s ears. The first of course is “Nixie tubes” with their warm cold war era ambiance and nostalgia inducing ...

Microchip has changed the name of its UK subsidiary that is working on nano-relay-based logic and memory for an EU ultra-low-power computing and memory project. Caldicot-based Microsemi Semiconductor ...

In order to guarantee an instantaneous trip on 100% of the line while maintaining the same level of security, communications-based logic is often used. A large number of variants have been developed, ...

Testing electrical components such as cables, relays, switchgear, breakers, etc. is very important to the reliability of an electrical system. ANSI/NETA MTS 2015 provides the best practice for the ...

The programmable logic control (PLC) is the controller for many industrial processes; it is tightly focused and optimized for the task due to its rugged electrical, software, mechanical, and thermal ...

Relays are clunky, switch slowly, have contact bounce, and make noise, both acoustically and electromagnetically, so why are they still used? Relays are clunky, switch slowly, have contact bounce, and ...
