Abstract :
Summary form only given. The magnetic components (transformers and inductors) are widely used, from high frequency switching power supplies to low frequency electric grid. There are different electromagnetic effects inside the magnetic components (such as the leakage inductances, parasitic capacitances, skin and proximity effects, etc.) which make the frequency response quite complex. There are several applications for which the modeling of the frequency response is quite useful. The FRA. (Frequency Response Analysis) techniques for advanced maintenance of big transformers of the electric grid are a good example of them. A full procedure of modeling the frequency response of magnetic components presented in the paper. Some diagnosis of power transformers based on this modeling is also presented.
