This paper presents the mathematical model of a single-phase multi-winding core type transformer taking into account magnetic hysteresis phenomenon based on the feedback Preisach model (FPM). The set of loop differential equations was developed for a K-th winding transformer model where the flux linkages of each winding includes flux Φ common to all windings as a function of magneto motive force Θ of all windings. The first purpose of this paper is to implement a hysteresis nonlinearity involved in the Φ(Θ) function which also accounts residual magnetic flux. The second purpose of this paper is experimental validation of the developed transformer model in a capacitor discharge test and several different values of residual magnetic flux.

This paper presents the results of the experimental and simulation investigation concerning the influence of remanence in the core of a single-phase transformer at the noload transient state. Experimental studies consisted of the discharge of the capacitor through the primary winding at several different values of the residual magnetic flux. The paper presents a model of the transformer test system, taking into account the magnetic hysteresis phenomenon based on the Preisach model with feedback. The model was used to simulate the transient and steady state of the test system, taking into account the value and the sign of the remanence in the toroidal tape wound core. It was concluded that the induction of remanence has a significant impact on the value of the inrush current. This model can be used for simulation of the transformer systems transient state, taking into account the magnetic hysteresis and the remanence.

Abstract-Sympathetic inrush current phenomenon occurs when a transformer is switched on in a power system network containing other transformers which are already energized. In this paper, the phenomenon of sympathetic inrush current is investigated using nonlinear-transient field-circuit coupled finite element formulation. The cases of the transformers connected in parallel and in series have been considered. The results obtained for a 31.5 MVA, three-phase transformer are presented and discussed in detail. This work also includes the investigation of parameters affecting the magnitude and duration of sympathetic inrush phenomenon, such as series resistance, switching-on angle, residual flux density and load conditions. These analyses provide a sound theoretical basis for a thorough understanding of the phenomenon.Index Terms-Sympathetic inrush phenomenon, finite element method, field-circuit coupling, nonlinear transient.
