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 ...

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 ...

New features for the Megger MPRT Protective Relay Test Set are now available. These improvements include improved system operating reliabilty, additional test capabilities and new features to the AVTS ...

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 ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.

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 ...
