Not long after I began contributing to Hagerty eight years ago, I wrote a detailed four-part piece on electrical relays and how they work in cars. You can still find the articles here (Part I: Why We ...

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

A freight train takes over a mile to stop — which means when engineers see danger on the tracks, it's already too late. That’s why railroad crossings are packed with deceptively complex tech: relays, ...

This technical primer breaks down defrost control board operation, key components, and practical troubleshooting steps every ...

Abstract: This paper develops a systematic method for the synthesis of electronic circuits which must realize symmetric Boolean functions. The ``fold-down'' method, originated by Shannon [1], solves ...

Abstract: This paper presents a novel methodology for directional overcurrent relays (DOCRs) coordination that effectively accounts for the transient topologies triggered by faster operation of remote ...
