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 ...

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 ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.

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 ...

GOOSE Messaging (Generic Object-Oriented Substation Events) is the most used aspect of 61850. Replace copper wires with digital one, turn that Lock Out Relay (LOR) into a latch bit in a relay and send ...

Pickering’s smallest miniature SIP reed relay with a power rating up to 80 Watts offers alternative to mercury wetted reed relays or electromechanical relays Leading manufacturer of high performance ...
