Abstract

In this paper an analytical model of continuously transposed cable (CTC) windings is proposed and short circuit condition in these types of windings is simulated. The proposed model is developed to calculate the current distribution in all strands of CTC windings in faulty and no-fault condition. The model is based on the finite element method (FEM) and takes into account the Â¿skin effectÂ¿ impact. Finally, the proposed approach is verified by experiment and some comparative numerical results are presented.
