Development of Partial Discharge Signal in Ester Oil Impregnated Paper

Abstract

Power transformer is the most exorbitant and controversially the most essential equipment. Insulation abortion in transformer can cause stretched term interruption to supply and loss of revenue and the important maintenance procedure. The power transformer consists of organic insulation like Mineral oil, pressboard and paper. In impecunious of bio- degradability and availability, ester oil is replaced by Mineral oil. The partial discharge is a tool for evaluate the insulation atrophy of dielectric materials. In this paper the results of a laboratory based experimental investigation of partial discharge activity in oil – impregnated paper. To guesstimate the statistical parameter for different electrode configuration like different configuration under open air gap condition.
