Partial Discharge Inception Voltage (PDIV) and Breakdown Voltage (BDV) characteristics of kraft paper insulation impregnated with canola oil containing ZnO (zinc oxide) nanofluid, under variations in multilayer configuration and impregnation time. The purpose of this research is to analyze the influence of ZnO nanoparticle concentration and multilayer structure on the dielectric performance of kraft paper insulation. The samples were prepared with one, two, and three layers of kraft paper and subjected to impregnation for 1 hour, 12 hours, and 24 hours. The electrical tests were performed using the AC Hipot Test method to determine PDIV and BDV values for each configuration. The experimental results indicate that increasing both the number of layers and the impregnation duration leads to a significant improvement in dielectric strength. The highest PDIV value of 2.348 kV and BDV value of 6.685 kV were obtained from the three-layer sample impregnated for 24 hours, corresponding to increases of 90.6% and 190.7%, respectively, compared to the control sample. These findings demonstrate that the combination of a multilayer insulation system and ZnOfilled canola oil impregnation effectively enhances dielectric strength, reduces the likelihood of partial discharge, and improves overall insulation stability. Therefore, canola oil-based ZnO nanofluid shows strong potential to serve as an environmentally friendly alternative insulating material to replace conventional mineral oil in transformer solid insulation systems.
