Inclusion of a White-Box Transformer Model in EMTP-RV
Transformer manufacturers make use of detailed (white-box) transformer models for calculating internal voltages during the lightning impulse test. Such white-box models could also be utilized in general transient simulation studies. This presentation describes the inclusion of one white-box model in EMTP-RV using DLL code. The resulting model is highly efficient and it can be used to study internal overvoltages in the transformer during network transients, e.g. swithing operations and lightning strokes. The visualization of internal voltages is achieved by a matlab-based tool.
