Protective relay testing verifies that installed relays will trip correctly under real fault conditions, confirming settings, ...

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 ...

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 ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

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.

One of the biggest trends in the switch and relay markets is the call for more options to help designers select the best switching device for their application. Other big asks are for longer life, ...

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 ...

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 ...
