Research on the deformation of transformer windings based on the analysis of short circuit reactance

Windings deformation of power transformer during operation will cause a change of short-circuit reactance, therefore,we introduce the finite element method to calculate the transformer short-circuit reactance.In this paper, a model of power transformers is established by using software ANSYS,and transformer reactance parameters are calculated. The test results of ANSYS simulation indicate that the accuracy and correctness is high, and can provide a theoretical basis for the detection of windings deformation of power transformer.
