Assessment of the resource consumption of oil-filled power transformer paper insulation based on updated aging integral

Abstract

Refinement of the aging integral formula is proposed. A com-puter model of insulation wearing out is developed using refined formula. Computer simulation of power transformer insulation wearing out over the next ten years of life is carried out.
