Differential protection have the most important role in protection of power transformers from internal faults. This paper discusses the power transformer modeling from differential protection aspect. Firstly the paper describes a low frequency transient model of power transformer and parameters of given model. Cases of inrush current, short circuit in protection zone and over—excitation were simulated. Finally, in all cases the harmonic content of the differential current is analyzed and appropriate conclusions are given regarding the performance of differential protection on the basis of these analyzes.
