“…Following the observations in the previous section, a Grey Box model based on limited information about the transformer geometry has been developed to study high frequency overvoltages existing on outside and inside terminals of the transformer [3], [4], [10].…”

“…The study of the winding geometry is another effort to estimate the elements of such a model [23][24][25]. The philosophy of such efforts is to model the geometry of a winding using Maxwell's equations to compute the inductance and capacitance matrices.…”

“…5 [12,15], where RH and R X present series resistances including cooper losses of each winding (skin effect and Joules losses), L H and L X present leakage inductance, R m and L m present core behaviour (including nonlinearity, saturation, hysteresis and other iron losses) and N H / N X is transformer ratio. The T-model of transformer is suitable for low frequency analysis (up to few kHz), while for analysis at higher frequencies more detailed transformer models should be used (such as Black Box, White Box and Grey Box) [14].…”
