Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

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 ...

Ideally a test engineer would connect a separate instrument to each test point of a Device Undergoing Test (DUT), thereby providing the highest performance and most accurate measurements. But this is ...

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 ...

Distributed generation, also known as embedded generation, is a hot topic at the moment. With more and more generation being connected to the network, those concerned with its stability have to deal ...

The Barrington Model Circuit Breaker Simulator was designed to be a convenient, lightweight alternative to operating high-voltage circuit breakers while testing the operation of substation protection ...

A May 2014 fire knocked out the Martin Drake Power Plant of Colorado Springs Utilities (CSU). The fire damaged all three coal-fired units, quickly disabling the entire 254 MW facility. The plant ...

Pickering Interfaces has announced a range of PXI and PXIe microwave relay modules capable of switching signals up to 110GHz in 50Ω. They will be reveals for the first time at IMS in San Diego next ...
