Statistical Analysis of AC Breakdown Strength Characteristics According to Nanofiller Content

It is known that the addition of nanoparticles to the insulator improves electrical and physical properties compared to the conventional insulator. In this paper, a short-term AC breakdown test was conducted on a material to which three contents (0.83, 1.25, 2 [wt. %]) of MgO nanoparticles were added to analyze the characteristics of nanoparticles added. Based on the results of the test, the characteristics of each material were statistically analyzed using the Weibull plot, contour plot, and box plot.
