Proper selection and effective testing can increase contact reliability in the end product while reducing the overall cost of using relays. Who said relays are pass�? While electromechanical relays ...

IDEC Corporation announces the release of its new HR5S safety relay module. This latest addition to IDEC’s family of safety devices gives designers and OEMs more options to provide better end user ...

Testing verifies that protection schemes meet their intended purpose, ensuring safety and system integrity. Function testing involves manual or electrical manipulation of components to confirm signal ...

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 ...

To simplify complex relay testing, the Megger Protective Relay Test Set (MPRT) provides built-in test routines, a touch-screen interface, and built-in transducer test capabilities. The unit displays ...

Megger’s new SMRT 36 smart protective relay test set is suited not only for testing today’s installations and legacy plant, but also for meeting the future challenges associated with testing the smart ...

An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...
