Abstract

Surface roughness and fractal analysis is carried out on the surface discharge patterns formed on epoxy nanocomposite, by harmonic AC voltages. The surface discharge patterns are obtained be adopting IEC(b) electrode configuration, and surface degradation levels are compared. It is observed that discharges initiated from the high voltage electrode propagates over the surface of the nanocomposites, the extent of discharge propagation are different for AC voltages with different harmonics and THDs. Surface roughness does not linearly increase with the increase in order of harmonics. Fractal dimension of surface discharge patterns in air medium varies between 1.4 – 1.72.
