Abstract

In this paper a model of a two-winding transformer based on the finite element technique is proposed. The model employs a T-equivalent circuit of the transformer. Local systems of equations are derived both for the case of a single-phase transformer and for the case of the three-phase transformer. Three most often used transformer connections are observed in the case of the three-phase transformer. These models of a two-winding single-phase or three-phase transformers will be used in an electromagnetic model for analysis of ground fault current distribution based on the finite element technique.
