Modeling of IM with stator winding inter-turn fault validated by FEM

In this paper a simple dynamic model for induction machines (IM) with inter-turn winding fault is established. Finite element method is used for parameter identification of the machine under fault condition. The proposed dynamic model is validated by time stepping finite element (FE) analysis. The dynamic model results exhibit the same trend as predicted by FE analysis for different fault insulation resistances. This model is well adapted for IM health monitoring and inter-turn fault diagnosis.
