摘要： A method for obtaining a power system phasor includes sampling a power system signal at instants determined by a nominal power system frequency to provide a plurality of data samples; using the data samples to estimate a phasor having an elliptical trajectory; generating a deviation formula representing a frequency deviation between actual and nominal power system frequencies; and using the deviation formula to perform a coordinate transform of the estimated phasor to provide a scaled phasor having a substantially circular trajectory. If the data samples are unevenly spaced, a method in another embodiment includes minimizing squares of errors between the unevenly spaced data samples and an approximating sinusoidal function of the data samples. Power system phasors can be used to detect turn faults by providing scaled current and voltage phasors; extracting fundamental voltage and current phasors; and applying a symmetrical component transform to the fundamental voltage and current phasors to obtain symmetrical component voltage and current phasors for use in determining the existence of a turn fault. Variance calculations and/or trigonometric function fits can be used to increase sensitivity of fault detection.

摘要： A method for detecting turn faults in an induction motor includes obtaining motor current and voltage waveforms and converting the motor current and voltage waveforms to digitized current and voltage waveforms. Fundamental phasors of the digitized current and voltage waveforms are extracted and, a symmetrical component transform is applied to the fundamental phasors to obtain symmetrical component current and voltage phasors including a negative sequence voltage phasor (V.sub.-) and negative sequence current phasor (I.sub.-). A fault injected negative sequence current (Ii.sub.-) is estimated according to the following equation: Ii.sub.- =I.sub.- -V.sub.- /Z.sub.- -Ir, wherein Z.sub.- is a characteristic negative sequence impedance and Ir is a residual injected negative sequence current. The existence of a turn fault is determined by comparing the estimated fault injected negative sequence current with a threshold fault injected negative sequence current.

摘要： A method for monitoring a rotor speed of an X-ray tube anode drive includes acquiring axial flux pickup data from the rotor, using the axial flux pickup data to provide a flux spectrum, and estimating the rotor speed by analyzing the flux spectrum. The step of acquiring axial flux pickup data can include situating an axial leakage flux pickup coil so as to pick up a flux signal from an X-ray tube anode drive rotor while the rotor rotates. An analog flux signal can be converted to a digital flux signal and a fast Fourier transform can be used to transform the digital flux signal into a flux spectrum. The flux spectrum can be used to estimate a drive frequency and a slip frequency and the speed can be estimated by subtracting the slip frequency from the drive frequency and dividing by the number of pole pairs of the X-ray tube anode drive.

摘要： A radio frequency (RF) or other form of detector detects discharges of an insulated system which can occur when electrical insulation becomes wet, for subsequent analysis and decision processes. Additionally, for RF detection, a frequency selector can be used to select a “quiet” region of the discharge spectrum before demodulation and further analysis and decision. Finally, redundant sets of such filters avoid the need to continuously reconfigure the detection system.

摘要： In a five-axis magnetic bearing, each of two combined radial and axial magnetic bearing structures includes a radial magnetic stator and a radial magnetic rotor. A shaft supports the rotors of the bearing structures. Each rotor and stator have an asymmetrical orientation such that the bearing structure is capable of creating a force in an axial direction when the bearing structure is excited. A creatable axial force of a first one of the bearing structures is capable of being in sufficient opposition to a creatable force of a second one of the bearing structures so as to maintain the shaft assembly in a desired axial position. The asymmetrical orientation may include, for example, a rotor being physically offset from a stator or a spatial distinction between a surface region of a respective rotor and a surface region of a respective stator. Examples of spatial distinctions include material extensions, notches, and holes. Each bearing structure can be controlled by four stator portions (actuators) with each actuator being supplied with current signals representative of a common mode axial force command and a respective differential radial force command.

摘要： An induction machine asymmetry detection instrument includes an interconnector and a voltmeter. The interconnector is configured to connect an electric source across a first terminal and a second terminal of a stator of an induction machine. The induction machine includes a rotor disposed for magnetic coupling with the stator. The interconnector is further configured to cause a flow of direct current between the first terminal and the second terminal of the stator during a rotation of the rotor when the induction machine is substantially unloaded. The voltmeter is connectable across the second terminal and a third terminal of the stator. A detection by the voltmeter of a meaningful voltage across the second terminal and the third terminal of the stator concurrent with the flow of direct current between the first terminal and the second terminal and concurrent with the rotation of the rotor serves to indicate an asymmetry of a portion of the induction machine.
