Sažetak
The paper presents an application of the reassigned Gabor time-frequency transform to the inductance inrush current transient analysis. A measurement setup is constructed and the measurement methodology is presented to obtain fully controlled transformer inrush current measurements. The measured data is analyzed by the reassigned Gabor time-frequency transform. The resulting time-frequency distribution of the measured signal shows how inrush DC component and harmonics change with time for different initial conditions. By extracting the stationary points from the reassigned Gabor transform, an algorithm for computing the time duration of the inrush is presented and applied to 88 measured transients.
