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 no-load 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,...
The paper presents development of an equivalent circuit model of a traction transformer with wound iron core intended for studies of transformer behavior in a traction drive system. The model accounts for the nonlinear BH characteristic and anisotropic properties of the wound core. Derivation of the mathematical model is based on the Lagrange's energy method. Each winding is modeled by a lumped conservative...
The paper presents the development of an equivalent circuit model of a traction transformer intended for studies into the diagnostics of interturn faults. The model accounts for the nonlinear B-H characteristic of the transformer core. The derivation of the model is based on the Lagrange's energy method. The values of model parameters were evaluated by means of 3D finite element model computations...
