RT Generic T1 Partial discharges and electric arcs on a polyethylene layer A1 Robles Muñoz, Guillermo AB Surface discharges and electric-arc on a polyethylene layer. The cylindric electrode is connected to a high-voltage source. As the voltage is raised, partial discharges appear at the base of the electrode giving a faint purple glow. A further increase in the voltage creates short arcs that do not reach the ground metallic plane. Finally, for voltages above 14 kV, the arcs are able to shortcircuit the electrode to ground.
