Monitoring changes in mechanical state of windings of power transformers caused by radial deformations

Autor: A. V. Prokhorov, E. I. Gol’dshtein

Publikováno v: Russian Electrical Engineering. 82:359-364

A method for monitoring of the mechanical state of the windings of power transformers, which enables one to identify the effects of the appearance of radial deformations of the windings by varying the phase-shift angle between the voltages of the pai

Determination of a phase shift between two nonsinusoidal signals represented by digital counts

Autor: E. I. Gol’dshtein, I. M. Katz

Publikováno v: Russian Physics Journal. 50:1032-1039

Applicability of the previously developed method of determining a phase shift based on the use of the Telleggen quasipower theorem for an analysis of nonsinusoidal signals is examined. Two new methods of calculating the phase shift between nonsinusoi

Discrete Fourier Transform for Short Samples in the Presence of Noise

Autor: D. V. Li, E. I. Gol'dshtein

Publikováno v: Measurement Techniques. 47:334-338

We consider the dependences of the error of a discrete Fourier transform on the length of the realization of the considered signal. The introduction of a procedure of making a preliminary determination of the period makes it possible to consider sign

Publikováno v: Measurement Techniques. 44:626-631

A universal method of determining the period of a complex multifrequency signal and a method of generating a signal with a specified period are described. The use of the method to determine the period of a wattmeter diagram when monitoring and diagno
