  author={Seyed Reza Karimpour-Mouziraji and I. Ahmadi},
Unbalanced voltages can result in adverse effects on equipment, which is intensified by the fact that a small unbalance in the phase voltages can cause a disproportionately larger unbalance in the phase currents. In this paper a 15 kVA 3-phase dry transformer has been analyzed using theoretical modeling. Specifically, modeling the transformer under nonlinear and linear loads under un-balanced supply voltage in 3D has been investigated. Transformer loss under linear loads is compared with non… Expand
