•2 transformer winding models for fast transients were implemented as Simulink blocks.•Both models complied satisfactorily with their functions when applied on a test case.•The selection of model depends on a balance between computer time and accuracy.•The new model blocks will facilitate future fast front transient studies. To date, programs available for the simulation of electromagnetic transients in power components and networks do not include transformer winding models able to simulate an impulse test response. This is an important omission, since the standard impulse test defines for most cases the highest dielectric stress that a power transformer will suffer once installed. In this work, two transformer winding models for fast transient analysis are implemented in Simulink: a lumped parameter model based on state-space equations and a distributed parameter model based on multiconductor transmission line theory and Bergeron’s method. A test case consisting of a 286 turns winding is provided to demonstrate the performance of the models implemented. Both models are applied to the computation of the transient voltage along the turns of the transformer winding considering lossless case and including series losses.
