Abstract::
In this work, we detected the defects of the asynchronous electric machine under normal conditions and without load by installing multi-layer sensor active materials at the stator (Terfenol-D and PZT-5H). The magnetic field in the stator deforms the magnetostrictive layers and this distortion in turn affects the piezoelectric layer, which leads to the polarization of this layer and the appearance of a potential difference between their terminals. We chose the finite element method for the numerical solution. This method is a more powerful and versatile numerical technique for handling problems involving complex geometries and inhomogeneous media.

Abstract::
In this work we tried to contribute in solving the problem of flashover in polluted high voltage insulators. For this purpose, metaheuristic methods, namely fireflies algorithm, have been used to solve the Obenaus equation which is practically the only mathematical model that simulates this phenomenon. The results obtained demonstrate the high precision of the approach used.
