Model Based Frequency Response Analysis for Characterization of Transformer Insulation

• This paper presents investigations on the possibility ofcharacterizing the transformer insulation by frequencyresponse analysis (FRA) technique. A lumped parameter circuit model was built for a single winding and for a model transformer. The proposed model was used to predict the effects of different characteristics of insulation on the frequency response of winding impedance. The simulated and measured responses of the model transformer are presented and discussed.
