Insulating oil is a liquid insulating material which acts as an insulating medium and coolant. Mineral insulating oil is the most commonly used liquid insulating material in oil-immersed transformer. In this paper, the critical characteristics of mineral insulating oil modified by nanomanterials and flame retardants are studied. Modified mineral insulating oil prepared by mixing the nanoparticles (ferric oxide, copper, and magnesium hydrate) and tripropylphenyl phosphate (IPPP) for various volume concentrations with mineral insulating oil by ultrasonic process. Various critical parameters such as flash point, fire point, breakdown voltage, Kinematic viscosity are analyzed.
