Inclusion of frequency dependent losses in transformer flux-current excursions
This paper presents a model for the frequency dependent losses in the transformer core for transient studies. The non-integer power series approach is extended to include the frequency dependent behaviour of the losses. The results obtained are compared with manufacturer's data and are found to give a very good fit.
