Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess the integrity of insulation in motors, cables, transformers, and other ...

A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up ...

Testing a circuit breaker is about judging reliability under fault conditions, not just checking continuity or voltage. A ...

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 ...

Solid-state relays provide robust solutions for electronic switching in load control applications and hold many advantages over electromechanical relays. New, emerging solid-state relay designs offer ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

ABB has installed more than 700,000 SPACOM relays used for power system protection and reliable power system operation world-wide. With the older generation of relays now aging, ABB is developing new ...
