In recent years, significant developments in nano-particles/fillers for electrical, thermal, and mechanical properties have been observed. In the present work, experimentally the dielectric and thermal properties of standard/nano-filled sample of enamel with Zirconia as filler have been critically examined. The dielectric loss (tan δ), dielectric constant (ε), insulation strength, partial discharge...
Low voltage stator windings of electrical machines are often realized by means of wires insulated by organic enamel. This kind of enamel can be subjected to partial discharges (PD) activity that could lead to breakdown condition the electrical insulating system so that the life time could be shorter than the expected one. In this research work, twisted pair specimens insulated by non corona resistant...
