SYSTEM AND METHOD FOR DETECTING GROUND BRUSH LIFTING
The present subject matter is directed to a system and method for detecting lifting of a ground brush of a generator of an electrical power system connected to a power grid so as to prevent damage to the electrical power system (e.g. bearing failure). The method includes monitoring, via at least one...

| description | The present subject matter is directed to a system and method for detecting lifting of a ground brush of a generator of an electrical power system connected to a power grid so as to prevent damage to the electrical power system (e.g. bearing failure). The method includes monitoring, via at least one sensor, a voltage signal of a rotor shaft of the generator. The method also includes determining at least one characteristic (e.g. amplitude and/or frequency) of the voltage signal for a predetermined time period. Further, the method includes determining whether the at least one characteristic of the voltage signal is above a predetermined threshold, wherein the at least one characteristic of the voltage signal being above the predetermined threshold is indicative of the ground brush being lifted. |
