Abstract:
The analysis of the distribution of electric field and potential along a real insulator under dry
and wet contamination’s conditions was carried out in this work. In order to examine the
influence parameters; the insulator format, the insulating material, the electrical conductivity
and the pollution distribution mode, and to see their effect on the electrical behavior of these
insulators, simulations were carried out on the Comsol Multiphysics 6.1 software. According
to the results obtained, it should be noted that the humid case negatively influences the
electrical performance of the insulator, independently of the type of material, pollution
distribution’s mode and the chosen profile. On the other hand, no influence is detected after
the change in the electrical conductivity value. In addition, the results of our research help us
to deepen our knowledge on the behavior of insulators of various materials; hydrophilic,
hydrophobic and superhydrophobic.
