Description
Purpose - The purpose of this paper is to investigate the applicability of a DC hys-teresis measurement on power transformer terminals for the subsequent hysteresis model
parametrization in transformer grey box topology models.
Design/Methodology/Approach - Two transformer topology models with two dif-
ferent hysteresis models are used together with a DC hysteresis measurement via the
power transformer terminals to parameterize the hysteresis models by means of an op-
timization. The calculated current waveform with the derived model in the transformer
no-load condition are compared to the measured no-load current waveforms to validate
the model.
Findings - The proposed DC hysteresis measurement via the power transformer ter-
minals is suitable to parametrize two hysteresis models implemented in transformer
topology models to calculate the no-load current waveforms.
Originality - Different approaches for the measurement and utilization of transformer
terminal measurements for the hysteresis model parametrization are discussed in liter-
ature. The transformer topology models, derived with the presented approach, are able
to reproduce the transformer no-load current waveform with acceptable accuracy.
