A friend once asked about the block of relays pinned to a board behind my car's dash. To him relays were the mysterious little boxes that some cars inexplicably required to operate a horn. More than ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

Differential protection is best understood as a fault control philosophy rather than a component category. The relay itself is secondary to the scheme it enforces. Once a zone is defined, the system ...

Interested in DIY a simple electronic impulse relay module? T. K. Hareendran designs an impulse relay circuit that mimics the functions of a conventional electromechanical impulse relay. This module ...

The real core of engineering, in addition to technical expertise, is the ability to articulate the inevitable tradeoffs and pros/cons of design alternatives, and then weigh these relative to each ...
