Tests of distance relay teleprotection schemes should check both relays simultaneously, including their communication link. This video shows a real test of a 110 kV overhead line. The protection was ...

DALLAS--(BUSINESS WIRE)--Smaller, lighter and with a higher output power than any other comparable three-phase instrument, Megger’s new SMRT 36 smart protective relay test set is ideally suited not ...

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 ...

To simplify complex relay testing, the Megger Protective Relay Test Set (MPRT) provides built-in test routines, a touch-screen interface, and built-in transducer test capabilities. The unit displays ...

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 ...

Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...
