Partial Discharges in Electrical Insulation
site.ieee.orgPartial Discharges • Once the electric stress in the void exceeds 3 kV/mm (at 100 kPa), electric breakdown (a ^discharge or flow of electrons) will occur in the gas • When the electrons hit the edge of the void, any organic material (polyethylene, epoxy, oil) will be gradually decomposed – aging • A discharge in air also creates ozone
