This paper deals with experimental characterization of creepage discharge to improve the electrical characteristics of oil/pressboard (PB) composite insulation system by thin solid layer coating such as epoxy resin and Teflon on PB surface under positive standard impulse voltage (1.2/50 µs) using a rod-plane electrode arrangement in mineral oil. To evaluate the creepage discharge properties according...
A polymer nanocomposite (P-NC) has been manufactured using different processes based on ultrasonication (US) and particles surface treatment. The moisture absorption was detected with different characterization method such as Fourier transform infrared spectroscopy, isothermal thermogravimetric analysis and electrical characterizations. The use of particle surface treatment allows decreasing O-H absorption...
Degradation profiles induced by partial discharges and those induced by oxygen plasmas are compared for polyamide/mica nanocomposites. Both the resistances to partial discharges and to plasmas improve with an increase in nanofiller content. On the other hand, the partial discharge resistance is not improved if mum-sized glass fibers are added to polyamide. In order to investigate these phenomena,...
