The aging behavior of transformer insulation Kraft paper aged in a natural ester oil, recently developed from palm kernel oil, is compared to the behavior of paper samples aged in mineral insulating oil. This study aimed to investigate the effect of the natural ester oil on the aging of cellulose insulation paper if used as an alternative insulating fluid in transformers. Thermally upgraded insulation...
Natural ester fluids have been synthesized from crude palm kernel oil for consideration as an alternative to mineral oil based insulating fluid. Chemical modification of the oil enhanced the physico-chemical properties of the fluid. This paper presents the statistical analysis of the AC electrical breakdown strength of the synthesized esters in comparison with the crude palm kernel oil sample. The...
This paper presents characteristics of dielectric fluids prepared from chemical modification of palm kernel oil ester as an alternative to mineral oil for use in HV electric equipment such as transformers. The palm kernel oil-based alkyl ester dielectric fluids were synthesized from palm kernel oil through epoxidation and esterification reactions. The functional groups in the alkyl esters were identified...
