This paper presents a novel approach to stator inter-turn fault detection using stray flux analysis. By using this method the location of stator phase-to-core or phase-to-neutral faults can be located with a acceptable accuracy. The basic concept of this new method can be implemented on the all three-phase rotating elements in the power systems for monitoring considerations. Results obtained by simulations with MATLAB show the effectiveness of the proposed method for detecting faulty coil(s).
