Investigation on mixed insulating fluids with nano fluids and antioxidants

Abstract

In the whole world the electricity plays a major role today. The important component in the power system is the transformer which is composed of solid and liquid insulation. Insulating fluids used in transformer decides the efficiency of transformer. Today we use mineral oil as insulating fluid but due to the increase in need of electricity the scarcity of mineral oil exist. The sudden replacement of mineral oil with other liquid is somewhat difficult for the researcher. First the natural ester and the silicone oil has the greatest disadvantage of high viscosity. In this paper an effort has been made to find the alternative solution with the concept of mixed insulating fluids. The paper also concluded with enhancing the critical parameters such as breakdown voltage, flash and fire point of individual and mixed insulating fluid with the suitable additives of nano material and antioxidants. For investigation mineral oil, sunflower oil, Rice bran oil and silicone oil are chosen. The critical parameters to be analyzed are flash point, fire point, viscosity and breakdown voltage.
