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 ...

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 communications can generally be divided into three primary categories. Clientserver communication is commonly used for monitoring, control, and reporting. GOOSE messaging provides high-speed ...

Protective relays are critical power systems components, and it is essential to design and use them properly to detect power system issues. As NETA-certified technicians, we must be familiar with the ...

Protective relay installations that are based on IEC 61850, the international communication standard for electrical substations, can now be tested with Megger’s MPRT test set. The IEC 61850 option ...

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 ...

Perhaps the most important feature introduced by microprocessor relays is that of continuous self-supervision. One of the classical problems of the older protection relays lies in the absence of any ...

Overfrequency protective relays and monitoring relays are devices designed to monitor the frequency of an electrical system. They detect when the frequency exceeds a predetermined threshold and ...

Complying with reliability standards requires considerable resource planning. The tools and suggestions provided here may help engineers conform to new generator relay loadability requirements. But ...

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 ...
