New Generator Protection Relay - MRG3

The new MRG3 is a generator protection relay with mains decoupling functions as well as overcurrent protection and earth fault supervision in one device.

On customer request we developed a new series of devices for generator protection applications on the basis of our High Tech Line platform. The devices are specially designed for mains parallel applications considering the different neutral point treatments.

 

The result are the following 6 types of relays.

 

 

MRG3:

With the functions, voltage protection [27,59], frequency protection [81U/O], vector surge function and frequency gradient protection (df/dt) [78]
