Abstract

Power transformers are among the most critical components in electrical energy systems, serving to convert voltage levels and ensure the reliable transmission of power. Therefore, modeling and analyzing possible transformer faults in advance is essential for maintaining system continuity and operational safety. In this study, a three-dimensional model of a laboratory-based power transformer was developed using ANSYS@ Maxwell. Manufacturer data were utilized during the modeling process, and electromagnetic analyses were conducted considering the core geometry, winding configuration, material properties, and associated losses. The model accuracy was verified by comparing the simulated turns ratio, no-load losses, and load losses with the factory test results. Subsequently, phase-to-phase and phase-to-ground short-circuit faults were simulated on the model. The variations in current, voltage, and electromagnetic force before and after the faults were analyzed in detail. The results reveal the impacts of fault conditions on magnetic saturation, winding stress, and voltage imbalance within the transformer. Overall, the findings provide valuable insight into the short-circuit behavior of power transformers and serve as a useful reference for the early detection of faults and the improvement of protection systems in power networks.
