Many electric utilities and power producers today have replaced, or are considering replacing, their aging electromechanical relays with new-generation, microprocessor-based relays.

Thanks to ongoing innovations in technology, electrical engineers' approach to motor protection has changed over the years. The traditional strategy to large AC motor protection (e.g., over 500 hp), ...

SEL merging units have integrated, local protection that works even if communications are lost between the merging unit and the relay. They can be paired with SV-supported relays (such as the SEL-421 ...

With the PSRuni multifunctional safety relay from Phoenix Contact, up to two safety functions can be monitored with just one device. The comprehensive coverage of common safety functions allows ...

This not only allows for the simulation of sophisticated auto-reclosure cycles but also offers the possibility to perform iterative closed-loop tests of one or more protection relays. Analyzing the ...

New York, USA, Dec. 06, 2024 (GLOBE NEWSWIRE) -- Market Overview: The global protective relay market size is projected to grow from USD 2.69 billion in 2024 to USD 4.59 billion by 2034, at a CAGR ...

As related to safety, this is a great improvement over earlier requirements of the Code, which did not call for any ground-fault relay. However, it must be noted that this level of ground sensing and ...
