|System Identification of Transformer′s Transfer Function |
|Abstract：A methodology to identify analytical expression of transformer winding′s transfer |
|function from frequency response is presented based on least squares. Some factors |
|influencing result are discussed. Then improvement steps are put forward to improve the |
|accuracy.
