Numerical calculations of three-phase transformer transients

A three-phase, two-winding transformer model is presented in this paper. Nonlinear magnetizing curves are piecewise linearized, while the input winding capacitances are lumped onto the transformer terminals. A stiff system of differential equations in a state space, describing the transformer transi...
