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 ...

New features for the Megger MPRT Protective Relay Test Set are now available. New features for the Megger MPRT Protective Relay Test Set are now available. These improvements include improved system ...

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 ...

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 ...

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 ...

A few weeks ago, I ordered a relay tester. Never had one, always wanted one. Whenever I doubt the proper functioning of a ...

Testing verifies that protection schemes meet their intended purpose, ensuring safety and system integrity. Function testing involves manual or electrical manipulation of components to confirm signal ...

Two simple tests can go a long way toward ensuring the reliability of today�s reed relays. The reliability of today�s dry-reed relays can approach or exceed that of electronic components in many ...

Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...
