dc.description.abstractThis study explored the application of CdSeTe quantum dots (QDs) in mineral oils for high-voltage applications through a comprehensive approach. CdSeTe QDs were synthesized using an organometallic method and added to mineral oil at concentrations of 1 mg/L (C1), 5 mg/L (C2), and 10 mg/L (C3). The samples' stability condition was monitored for a long period, and physicochemical tests were performed. Experimental results show that QD-modified oils have enhanced electrical properties compared to the base oil. The breakdown voltage was in the range of 17 to 23 kV for the base oil, while the breakdown voltage was in the range of 20 to 39 kV for the QD-modified (C2) insulating fluid sample. Throughout the 25-day monitoring period, the QDs were found to be properly dispersed in oil and free of aggregation in all samples. Values such as density and viscosity remained fairly constant due to the relatively low concentration ratio. However, an increase in total acid number was observed with increasing concentration. These results imply that QD-enhanced insulation oils may have applications in high-voltage applications in the future. The main innovation of this study lies in demonstrating that CdSeTe QDs can significantly enhance the dielectric strength of mineral oils while maintaining their essential physicochemical properties, offering a novel approach for improving insulation performance in high-voltage applications.en_US
