“…The sum of these large thermodynamic stresses is very dangerous for the coil in short-circuit condition (Zhai et al, 2022). Bal et al (2019), the finite element method (FEM) is used in simulation to analyze the electromagnetic transients of the Ansys three-phase oil type distribution transformer simulation program. Results are presented in terms of losses, voltages, currents and magnetic flux of the transformer.…”

The study used the Finite element method (FEM) by ANSYS 3D software to calculate the distribution of electromagnetic force (EMF) and temperature on the high voltage and low voltage windings (HLVWs) of the amorphous steel core 3 phase transformer (ASCT) which has a power of 1000kVA –22/0.4kV under different load cases: No load, full load and short circuit (SC). The obtained results show the exact temperature distribution and location where the highest temperature is found on the HLVWs of ASCT. From the analysis of the temperature distribution on the HLVWs, it is shown that when the transformer falls into an SC fault, it causes the greatest EMF and thermodynamic force, causing extremely heavy consequences for the transformers. The obtained results help designers, manufacturers, and operators have the most suitable options to improve strength of SC and increase the life of the transformer.

“…However, their work did not explicitly address the distribution of the leakage magnetic field or the axial and radial forces within the transformers. Bal et al (25) used the FEM embedded in ANSYS Maxwell simulation program to analyze the electromagnetic transients and compute the losses, voltages, currents and magnetic fluxes of a three-phase oil-type distribution transformer with a capacity of 25kVA. Li et al (26) presented the distribution of EMF in a three-phase power transformer of a 50MVA/110 kV under short-circuit conditions via the FEM.…”

The aim of this study is to examine and analyze the axial and radial forces, electromagnetic forces (EMFs) acting on the low and high-voltage windings of an amorphous core transformer via the two different approaches: an analytic approach and a 3-D finite element method (FEM). Firstly, the analytic method is proposed to analyze the distribution of leakage magnetic field in the magnetic circuit and the forces acting on the transformer windings. The FEM embedded in the Ansys Maxwell tool is then proposed to compute and simulate the axial and radial forces under three different operating conditions: no-load, rated full-load, and short-circuit. The obtained results from two different methods such as the rated voltage, rated current, short-circuit current, axial and radial forces and EMFs in the low and highvoltage windings are finally compared to illustrate an agreement of methods. The validation of the methods is applied on a three-phase amorphous core transformer of 1600kVA-22/0.4kV.
