    摘要： A load balancing system includes a transformer having a plurality of integrated sensors. A control system that may be embedded within the transformer is in electrical communication with the plurality of sensors. The control system is configured to estimate or determine the state of health of the transformer. The state of health of the transformer is based upon signals generated via the plurality of sensors. A load request that may be received that is compared to the state of health of the transformer to determine if the transformer can support the load request. The control system determines whether or not the transformer can provide electrical power based upon the estimated state of health of the transformer and in response to the load request.

    摘要： A system configured to monitor an operating electrical device includes a testing channel coupled to the device. The device is coupled to an electric power source through at least one electric power transmission channel. The power source is configured to transmit electric power at a first frequency. The testing channel is coupled to the power transmission channel. The system also includes a signal generator coupled to the testing channel. The signal generator is configured to inject testing signals into the testing channel at a second frequency that is greater than the first frequency. The system further includes at least one apparatus magnetically coupled to the power transmission channel. The magnetically coupled apparatus is configured to present a first impedance to the electric power at the first frequency and present a second impedance to the test signals at the second frequency. The second impedance is greater than the first impedance.

    摘要： A permanent magnet (PM) machine includes a plurality of reconfigurable fault condition mechanisms disposed within a stator core portion, the plurality of reconfigurable fault condition mechanisms together automatically reconfigurable to reduce fault currents and internal heat associated with the PM machine during a fault condition. The plurality of reconfigurable fault condition mechanisms are disposed solely within the stator core portion according to one embodiment to automatically reduce stator winding fault currents and internal heat associated with the PM machine during a fault condition. A method of reconfiguring the fault condition mechanisms upon detecting a fault condition includes the steps of 1) selecting the plurality of reconfigurable fault condition mechanisms from a) a plurality of rotatable magnetically anisotropic cylinders disposed both within a stator back iron and stator slot openings, and b) a plurality of rotatable magnetically anisotropic cylinders disposed within a stator back iron and a sliding shield disposed with a stator slot opening portion of the stator core, and 2) reconfiguring the plurality of fault condition mechanisms together to automatically reduce fault currents associated with the PM machine upon detection of a fault condition.

    摘要： A method for evaluating core stack pressure includes: positioning a magnetic yoke near the core, the magnetic yoke being wound by an excitation winding; supplying current to the excitation winding to inject magnetic flux into the core; measuring a signal resulting from the injected magnetic flux; and using the measured signal to evaluate the core stack pressure. A system for implementing the method includes the magnetic yoke; a current supply for supplying the current; a sensor for measuring the signal; and a computer for using the measured signal to evaluate core stack pressure.

    摘要： A power generator that operates at a reduced temperature level includes a flux shunt that reduces the amount of fringing magnetic flux axially impinging upon a stator, flange, and multiple keybars during operation of the generator. By reducing the amount of axially impinging flux, the flux shunt reduces an operating temperature of the stator and flange and reduces a voltage differential between keybar voltages induced by the flux in the multiple keybars.
