Abstract: Frequency response analysis (FRA) has become a widely accepted tool to detect power transformer winding deformation due to the development of FRA test equipment. Because FRA relies on graphical analysis, interpretation of its signature is a very specialized area that calls for skilled personnel, as so far, there is no reliable standard code for FRA signature identification and quantification. Many researchers investigated the impact of various mechanical winding deformations on the transformer FRA signature us… Show more

“…In addition of improving the accuracy, phase function increases the convergence speed too. Even with all useful effects of the phase function, it is not often considered by researchers, for the sake of simplicity, increasing the convergence rate or evading a multiobjective problem . For simplifying the problem at first level, the number of considered frequency points decreased and only 1/10 of all frequency points are used at this level.…”

“…Even with all useful effects of the phase function, it is not often considered by researchers, for the sake of simplicity, increasing the convergence rate or evading a multiobjective problem. [14][15][16][17][18]22,24 For simplifying the problem at first level, the number of considered frequency points decreased and only 1/10 of all frequency points are used at this level. The second objective function computes the normalized Euclidean distance among the magnitude of the reference frequency points and the calculated FR points.…”

“…In general, methods of prognostic and diagnostics can be categorized into physics-based, data-driven, and hybrid approaches [3,4]. The physics-based method uses a specific physical model to represent the normal machine state and detects the potential failure types based on the deviations between the actual system and the physical model [5][6][7][8][9][10][11]. Hashemnia et al [5,6] used frequency response analysis diagnostics to improve the fault detection of power transformer winding.…”

“…While many researchers investigated the impact of various mechanical winding deformations such as axial displacement [17,18], buckling deformation [19][20][21], disk space variation [22] and short circuit turns [23] on the transformer FRA signature, no attention was given to the impact of transformer insulation aging and various bushings faults on the FRA signature [20,24,25]. In this paper, the geometric dimensions of a three-phase transformer including detailed transformer windings, insulation system and bushings are simulated using 3D finite element modelling (FEM) that allows the extraction of equivalent electrical circuit parameters of the transformer before and after applying a physical faults to the model.…”
