Testing relays and their circuits in vehicles doesn’t always require a trip to the bench. With a few simple tools and ...

This test circuit for electromechanical relays uses a microcontroller to control the relay under test through an optocoupler. A power supply and load produce current in the relay contacts.

This equipment is extremely easy to use. You just set the test values (current, voltage, phase angle, frequency) and activate the output. When the relay's operation is detected, the chronometer will ...

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

Megger’s new SMRT1 smart protective relay test set is suited not only for testing older installations and legacy power plants, but also for meeting the future challenges associated with testing the ...
