Abstract :
In this paper the overvoltages produced by switching the primary side of reactor loaded transformers are simulated using the Electromagnetic Transients Program (EMTP). Attention is focused on transformer modelling. Five general three-phase transformer models are used and from the results obtained, and comparisons with field tests, positive conclusions concerning the reliability and the accuracy of these models in the study of switching fast electromagnetic transients are drawn
