Testing relays is both an art and a science. As relay technicians inevitably learn in the field, pure theory-based understanding of protective relays is not nearly enough for the real-world situations ...

Many electronic designs can take advantage of the improved performance of solid-state relays (SSRs) relative to that of electromechanical relays (EMRs) that perform the same circuit function. OptoMOS® ...

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 ...
