| Summary, etc. biblio.abstract | In high-voltage transformers, liquid insulation serves<br/>as both an insulator and a cooling agent. For many<br/>decades, transformer oil has been the traditional<br/>choice for this purpose. Despite its high quality insulating properties, mineral oil poses several environmental<br/>drawbacks. Researchers are exploring alternative insulating fluids for high-voltage applications, considering<br/>both environmental impact and insulating properties.<br/>With the increasing demands for better electro, physical and chemical properties of vegetable insulating oils<br/>used in high-voltage power transformers, enhancing<br/>these oils with nanoparticles has become a prominent<br/>area of research. The present study investigates groundnut oil (GO) and mustard oil (MO) as base fluids for<br/>insulation oil by incorporating zinc oxide (ZnO) nanoparticles. It analyses the effect of varying concentrations of ZnO nanoparticles on the electro-physical and<br/>chemical properties of the oils. The analysis reveals<br/>several significant enhancements in the properties of<br/>the oils when incorporated with ZnO nanoparticles.<br/>The result shows that the enhancement of the dielectric<br/>strength of the oil can withstand electrical stress without breaking down. Further, the impulse breakdown<br/>voltage, which evaluates the oil’s ability to withstand<br/>high-voltage pulses, has significantly improved. The<br/>study observed a decrease in dissipation factors, representing reduced energy losses as heat within the oil,<br/>and a decrease in viscosities at high temperatures, implying improved fluidity and efficiency in high-temperature<br/>conditions. The interfacial tension improves, indicating<br/>better interfacial tension between the oil and water<br/>molecules. The findings suggest that vegetable oil-based<br/>nanofluids, with finer characteristics, have a high potential to replace traditional mineral oils. |
