The paper study a novel approach which is developed and validated for Permanent Magnet Synchronous Motor (PMSM) motor with demagnetization fault. The analytical model is derived for the calculate the magnetic field distribution Permanent Magnet Synchronous Motor including with demagnetization fault to evaluate the backelectromotive force (EMF) induced and the electromagnetic torque in a Permanent Magnet (PM). The proposed model is used to analyze the effect of parameters (the magnetic field distribution, the back-EMF induced and the electromagnetic torque) by a finite element (FE) simulations.

Keywords - Finite element method (FEM), Permanent Magnet Synchronous Motor (PMSM), Demagnetization fault.

In this study, the effect of different applied voltages, wetness and polluted conditions on the surge arrester leakage current was evaluated using measurements and simulation models. In metal oxide surge arresters, leakage current usually flows across the arrester under normal operating condition. Leakage current is one of the factors which contribute towards degradation of surge arresters. The behavior of leakage current in a metal oxide surge arrester during normal operation, under different voltages, wetness and pollution conditions were analyzed. An 11 kV surge arrester model in three-dimensional space was subjected to finite element analysis (FEA) to determine the leakage current under different conditions...........
