High‐frequency electromagnetic transients modelling of voltage and current distribution due to electromagnetic transients are of great importance in transformer design. In this study, a 2D and 3D finite‐element, coupled field‐circuit and modified detailed model is introduced for high‐frequency electromagnetic transient studies in split‐winding traction transformers. The proposed coupled field‐circuit approach uses a 2D finite‐element model that is coupled with an external circuit to analyse the electromagnetic transient behaviour of the split‐winding traction transformer. Also, a detailed model is introduced for this type of transformer and its results are compared with the introduced coupled field‐circuit model and complete 3D finite‐element model. After validating the introduced models, the models are employed to analyse the frequency response of the split‐winding traction transformer.
