Etude et optimisation des décharges partielles dans un modèle de condensateur à différentes températures

Abstract

In this paper, the partial discharge on models of all-film capacitors impregnated with liquid impregnating undegased is measured and the effect of temperature was examined. The partial discharge evolution in mixed dielectric is multifactorial process. The initial potential as well as the temperature are known to influence the partial discharge  evolution. The present paper aims at demonstrating the interest of using the design of
experiments methodology for the study of such processes, in view of their modeling and optimization. The obtained result is a mathematical model capable to identify the parameters and the interactions between factors.
