Etude de l’isolation dans les grands espaces d’huile

Abstract

Our memory has been made for the calculation principle of electric field in the great distances of oil. The first step of this work to be made it is the model of simulation that établait and calculated by the comsol software 3.5a 2D to compare both cases studies: cas1 (80 mm of diameter) and cas2 (20 mm of diameter) through this change we compare the results of calculations of electric field and the safety margin. Finally we find that the good location (good financial situation) this present in him cas1, what implies a validation of insulation, and to exclude the appearance of a partial discharge.
