Pickering Interfaces (Clacton-on-Sea, UK) has introduced the PI-MXT90-100 test tool that identifies faulty relays on its complex PXI switching matrices. The diagnostic tool uses a test adaptor and a ...

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 ...

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 ...

Push-to-Test Button Electromechanical Relays are devices that incorporate a manual pushbutton feature, allowing users to test the relay circuit. This functionality enables operators to verify the ...

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 ...

IEC 61850 is the new international communication standard for substations. The main goal of 61850 is to obtain interoperability between different protective devices from different vendors. IEC 61850 ...

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, ...
