Abstract

To study the transient interaction between the transformers and the power system is essential use very accurate transformer models considering the dependence of damping with frequency. In this work the fundamentals of transformer parameters calculation for high frequency transients using finite elements method (FEM) are reviewed and a promissory time-domain equivalent circuit is proposed based in the analysis of transient measurements results obtained by the CIGRE JWG A2/C4.52 in two transformers manufactured by WEG in Mexico.

Memorial and Acknowledgements

In first place we want to dedicate this work to Robert Degeneff, that passed away this year. Robert was pioneering in developing high-frequency transformer models and shared generously his knowledge and experience with us for more than thirty years. Secondly the authors would like to thank Bjorn Gustavsen, Enrique Mombello, Oliver Sterz, Tobias Röhrl and Anniyappan Palani for their support and many fruitful discussions on transformer modelling in the last years working together in the CIGRE JWG A2/C4.52.
