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 ...

Verification and diagnosis of complex switching operations in a test system has been made easier with the introduction of built-in self-testing capabilities to select models of Pickering Interfaces' ...

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 ...

An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

Smaller, lighter and with a higher output power than other three-phase instruments, Megger’s SMRT 36 smart protective relay test set is suited not only for testing today’s installations and legacy ...

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 ...
