Abstract
This paper describes an electromaanetic circuit model of three ohase transformers capable of includina ferromacanetic non-linear effects includinga hvsteresis, suitable for anv number of windinas with a variety of interphase connections and applicable to any magnetic circuit confiauration. In particular, three of the common types of magnetic circuits are considered i. e. (1) bank of sinqle phase cores (2) three limbb core and (3) five limmb core. The model is applied to tne solution of the inrush currents in a variety of situations and the results are shown to compare favourably with experimental results.Keywords
