1. Introduction and application
The generator rotor protection relay MRR1 combines
rotor earth fault protection, excitation over- and undercurrent
protection as well as rotating diode failure protection.
Thus providing a powerful protection regarding the rotor
of synchronous generators, covering the following
ANSI codes:
37 DC undercurrent relay
40 Field relay
58 Rectification failure relay
64 Ground detector relay
76 DC overcurrent relay
The MRR1 is recommended for synchronous generators
and motors above 1 MVA rating.
The rotor earth fault element detects high- and low resistance
earth faults of the rotor winding. It is equipped
with two stages, one for alarm, one for trip.
The excitation current protection element supervises the
DC excitation current of brushless excitor machines.
The protective functions are: Undercurrent, overcurrent
and ripple detection for diode failure protection.
