Different Approaches for Mathematical Evaluation of Resorption Currents in Nanodielectrics

The main goal of this research is to introduce three different kinds of mathematical methods for evaluation of dielectric resorption. These methods will be applied on dielectric contains filler with nano- dimensions. Dielectrics which contained different amount of nano- filler SiO
₂
have been prepared for this study (0, 0.25, 0.5, 0.75, 1.5 and 3 percent by weight). The process of sample production is described in detail. The average values of resorption currents were investigated by the method of Reduced Resorption Curves (RRCs), by the method of determination of the area over the curve and by the method of tangent determination. Individual methods are described in detail with all mathematical formulas, definitions, and illustrations. Selected methods may be used for evaluation of the behavior of the residual charge in solid insulation.
