Sažetak
The existing wide band transformer models are often too complex or they require confidential information on transformer geometry. Therefore, in this paper two state of the art wide band transformer models derived from accessible information to the transformer purchaser are described: a Black Box model based on sweep frequency response analyser (SFRA) measurements of the transformer’s admittance matrix and a Grey Box model based on a finite elements method (FEM) calculation, derived from limited information about the transformer geometry. Furthermore, an application of these transformer models aiming at questioning the measurements performed when purchasing a transformer such as lightning surges transfer and SFRA measurement is presented.
