In this work the partial discharge (PD) patterns acquired during electrical aging tests performed on twisted pair specimens prepared by winding wires having conventional or nanostructured enamel insulation are compared. The conventional enamel is polyamide imide, while the nanostructured enamel is a polyamide-silica nanocomposite. The tests have been performed applying sinusoidal voltage at different frequencies. The outcome shows interesting features of the PD activity monitored during the tests allowing a comparison between the two different insulating systems.

Abstract
In this work the partial discharge (PD) patterns acquired during electrical aging tests performed on twisted pair specimens prepared by winding wires having conventional or nanostructured enamel insulation are compared. The conventional enamel is polyamide imide, while the nanostructured enamel is a polyamide-silica nanocomposite. The tests have been performed applying sinusoidal voltage at different frequencies. The outcome shows interesting features of the PD activity monitored during the tests allowing a comparison between the two different insulating systems.
