Abstract
We have already proposed a transformer model for transfer voltage, which consists of the EMTP TRANSFORMER model simulating the electromagnetic transfer component and some capacitances simulating electrostatic transfer component. The value of various parameters of this model are calculated from the actual measurements entailing no numerical calculations and help in understanding their physical relevance. In the subsequent discussion, however, we found it important to consider the frequency dependence of leakage inductance and core loss. This paper shows frequency dependence from tested results for many transformers, and studies the validity of the new transformer model by comparing the transformer model based on the frequency dependence with the tested results. The model is represented in the MODELS language description.
