In general, insulating oil serves as an insulation and cooling medium of power transformers and different High Voltage (HV) application. The properties of insulating oil like breakdown voltage (BDV), viscosity, flash point and fire point are enhanced by adding of different additives in an optimal way. In this work, a mathematical model has been developed by using Lagrange interpolation technique for predicting the critical properties values in different volume concentrations (in Vol %). The predicted critical properties are compared with the set of measured data. Based on this approach, accuracy of predicted value has been obtained in between the two available measured data in two known different volume concentrations. From the volume concentrations (0-0.01%), the error seems to be negligible. Hence, Lagrange interpolation technique is considered as a reliable technique for predicting the intermediate value for different concentrations of nano powder doped insulating oil used in different HV power apparatus.Keywords

Transformer is one of the cost effective and critical component in high voltage (HV) electrical system network. The quality of mineral oil is the key parameter to determine the health of the transformer. Globally, electrical and physical parameters of mineral oil are considered as the most primitive critical parameters for monitoring the transformer throughout the year. In this paper, electrical parameters like AC breakdown voltage (BDV), volume resistivity and physical parameters like flash point and fire point of new and aged mineral oil are analyzed by dispersing TiO2 nanoparticles in mineral oil under different vol.% concentration. It is found that, new mineral oil with TiO2 nanoparticles shows enhanced BDV compared with base mineral oil. In addition to this, volume resistivity, flash point and fire point also shows improved results with TiO2 nanoparticles.Keywords
