Develop the thermal and electrical transformer oil by Barium Titanate nanopowder Ba/TiO3 addition

In this paper, Barium Titanate cubic nano powder Ba/TiO3 is added to transformer oil in order to enhance the electrical insulation and thermal conductivity of Barium Titanate nano oil (BTNO). Thermal conductivity, breakdown voltage, and AC resistivity of samples for pure oil and five percentages (0.01, 0.02, 0.03, 0.04, and 0.05%) w/w were measured. However, Oleic acid as a dispersing agent was added in a ratio of 0.02 w/w to 100 ml. of oil. It was discovered that BTNO had up to 1.5 times pure oil's thermal conductivity, breakdown voltage, and AC resistivity. The addition increased the oil's electrical resistance and internal cooling capacity. Including nano powder increased the useful life of the used oil and decreased the requirement for routine maintenance. Furthermore, it is strongly suggested—but with caution—to add oleic acid to manage the dispersing agent. Therefore, carefully monitoring the dispersion agent's addition is highly advised.
