dc.description.abstract Transformers are meticulously used in power system and for century the mineral oil is used as dielectric, which performs superior function such as insulation and heat dissipation (cooling). The availability of petroleum resource and disposal methods (incineration) may introduce panic threads to human life and environment. On the other hand the deterioration of transformer insulation system will affect the life and stability of power system. This work envisages the optimality of critical characteristics enhancement of mineral oil and natural ester with high performance antioxidants (natural and synthetic) and lubricating oil additives. The enhancement percentages were calculated 2 % compositions of antioxidants and lubricating oil additives. The electrical, physical and thermal properties like breakdown voltage, viscosity, flash point and fire point are calculated for the samples before and after addition of antioxidants and lubricating oil additives. The enhancement of fresh transformer oil is carried by adding multiple combinations of antioxidants with different mechanisms like free radical scavenging, metal chelating and synergism. The critical parameters like breakdown voltage, viscosity, flash point, fire point acid value of the samples are calculated using before and after additives according to IEC and ASTM standards. The recorded parameters prove that the performance characteristics of natural ester oil shows superiority against mineral oil when used with multifunctional additives. en_US
