Electrical treeing and morphological analysis of epoxy nanocomposites with different concentrations of silica nanofillers

In high voltage equipments, insulation systems are the most vital parts to prevent any discharges from occurs around the protected systems. However, the discharges in the form of electrical treeing can easily occur when there are existences of impurities, voids or defects in the insulation bulk. Th...
