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 ...

Electromechanical components such as relays and switches often must undergo endurance tests that verify their reliability and safety. Regulatory standards typically have compliance criteria that ...

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 ...

The essence of the circuit is for the input of tone and signal to provide an activation for the relay switch. Relay – an electrically operated switch where the current flowing through the coil of the ...

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 ...

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 ...

ABB, the original FT switch manufacturer, continues to deliver a product for in-service testing of relays, meters and instruments by any conventional system. ABB has announced the 50-year anniversary ...
