Description: This work is focused on the problem of modelling power transformers. Accurate models of these components are necessary to improve simulations that are characterized by different frequency ranges. This is of particular importance for frequencies which involve interaction between components of the electrical system. This paper compares two different approaches to modelling power transformers and highlights the tradeoffs associated with each method. The model parameters for both methods are determined from data obtained from frequency response analysis (FRA).
