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.

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.
