May 20, 2009, UK -- Protective relay installations that are based on IEC 61850, the new international communication standard for electricity substations, can now be tested easily and conveniently with ...

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

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 ...

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, ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...
