Abstract: A generator assembly may include a bearing liner and a bearing retainer configured to reduce vibration response in a bearing assembly under high frequency operation of a rotor. The bearing liner may be configured to provide a clearance between the bearing assembly and an adjacent housing/bearing liner to prevent high vibration output from the bearing assembly on for example, the rotor shaft. The bearing retainer may include a recess to accommodate axial movement of the bearing assembly in response to rotation of the rotor. In some embodiments, the bearing retainer may include a dampener to dampen contact of the bearing assembly with the retainer.

Abstract: An electrical power system may comprise a power source, an electrical load and an interconnection path between the power source and the electrical load. At least one power-source current transformer may be positioned at the power source. At least one remote current transformer may be positioned remotely from the power-source current transformer so that a portion of the interconnection path is between the power-source and the remote current transformer. A control circuit may be interposed between the power-source and remote current transformers and may be responsive to current imbalance between the power-source and remote current transformers to disconnect the power source from the electrical load in the event of such imbalance. The at least one power-source current transformer may comprise a secondary winding having first and second ends, and a resistor connected across the first and second ends.
