“…The integral and differential equation can be solved by using FEM analysis [11]. In electrical engineering, FEM is most commonly used for the magnetostatic analysis, electromagnetic analysis and to determine the thermal characters and conductivity [12]. Reactance can be calculated accurately by using numerical method like FEM [13].…”

Transformer is one of the main equipment in the power system and power quality of the power system mainly depends on the working of the power transformer. Leakage reactance is one of the main parameters of the transformer. The design of the transformer has a significant impact on the leakage reactance of the transformer. The mechanical strength of the transformer mainly depends on the leakage reactance of the transformer. This paper investigates the leakage reactance of the transformer in normal conditions and during the axial displacement of the high voltage and low voltage windings using finite element analysis. Normal results of finite element analysis method are also compared with the experimental short-circuit test. Results show that leakage reactance of the transformer exponentially proportional to the displacement of the windings. It is observed that with the axial displacement of the 6% of the winding, leakage reactance increased by 10%. Results also show that effect of the axial displacement in high voltage and low voltage winding is almost same.

“…Specific core loss, which is the core loss per kg weight of material, is an important property, as this will determine the final core loss of the transformer, after its assembly. Lower the specific core loss, higher will be the cost [4], [5] As Eddy current loss can be reduced by proper assembly of the core laminations, minimizing Hysteresis loss will effectively reduce the overall core loss. The core material and its dimensions are generally selected based on the requirement and analytical calculations.…”

This article focuses on the optimization of process parameters such as core area, core material and voltage for the design of power transformer. It employs Taguchi orthogonal array technique for designing the experiments and its analysis. Utility transformers are usually specified with the losses associated at design stage. The area of the core cross-section applied voltage, as well as the core material all has impact core loss deterioration. The impact of such variables influencing core loss is investigated by executing the model. A small proportion of core as well as the coil assembly experiments is simulated using the Taguchi approach with the orthogonal array. In this study, the core as well as the coil assembly of an 8MVA, 33/11KV, 3 Phase Transformer is modelled in ANSYS MAXWELL software. MINITAB software is used to assess the program's anticipated core loss in order to discover the optimal arrangement for three control variables.

“…Using ANSYS Maxwell software, a real transformer model with 3 inputs and 5 outputs has been studied. Before applying the software modeling, studies have been done on a real transformer [6]. The accuracy of different models of numerical methods has been investigated in order to calculate transformer's no-load losses.…”

Transformers, one of the most important elements of energy transmission and distribution systems, can be produced as a result of high cost and long-term studies. It is necessary to know the mechanical, electrical and magnetic properties of a transformer in the manufacturing process. Modeling of the transformers to be designed with a reliable simulation program in order to operate at targeted values and efficiency is important in terms of ensuring test criteria and minimizing the problems that may arise later. Thanks to advanced computer techniques, it is possible to identify design errors and correct them through a simulation program. In this paper, ANSYS Maxwell 3D software based on Finite Element Method (FEM) and widely used in transformer simulation was used. With this program, it is aimed to investigate the magnetic field density, magnetic field intensity, magnetic flux lines, current density values in the coil and core of the transformer and the effects of these values on transformer losses. Considering the nominal values of the single phase 90 VA transformer, its electrical and physical values were measured by experimental studies in the laboratory environment, and the necessary parameters and values were calculated based on these measurements. The theoretically calculated values are compared with the experimental study results and the values calculated with ANSYS Maxwell program. It was observed that the experimental study results and the results of the model created in the program confirmed each other.
