Influence of the Magnetic Steel Frame on the Efficiency of Short-circuit Faults Detection in Induction Motors through Harmonics of the Neighboring Magnetic Field

This paper studies the influence of the magnetic non-linear frames in the detection of the short-circuit faults based on the investigation of the magnetic field in the induction motors neighboring. The conclusions are based on the comparison of the finite element results obtained with three models: without frame, an ideal closed frame with very important shielding effect, and a frame with two opposite windows, whose radiative behavior is not so different than in the case of real frames.
