Modelling is a useful technique able to provide a suitable knowledge about the behaviour of all the devices operated at high frequencies. This thesis approaches this topic to the case of the transformer. A state of the art about high-frequency modelling is summarized and the most relevant research works are analysed. By using a 4 kVA three-phase power transformer, a set-up facility and the associated methodology has been proposed in order to develop a method able to obtain both the low and high-frequency models. The obtained model can be synthesized using passive LCR circuits. The accuracy of the model is then evaluated using the set-up facility. In initial experiments, the classic low-frequency model is put to the test in order know the maximum frequency at which the model can be used. After that, a new high-frequency model is proposed and its response is evaluated and validated with measurements.
