Investigation on Activation Energy and Temperature Conductivity Dependency of Laboratory prepared Mixed Insulation Samples

Abstract

In this paper mineral oil and vegetable oil have been blended in a certain ratio for preparingfive types of liquid dielectrics in laboratory to investigate their performance as liquid insulation. Then those mixed dielectrics were subjected to time domain dielectric response analysis through PDC measurement. Further from the recorded PDC data, conductivity of each sample has been calculated and compared with the pure mineral oil and vegetable oil. Moreover to realize the temperature effect, PDC data has been recorded in three distinct temperatures. From these data at 25°C, 50°C and 70°C the temperature conductivity dependency of the prepared samples has been investigated. After that activation energy of the prepared samples has been analyzed through PDC measurement using Arrhenius equation.
