Abstract :
Electrical tree formed in XLPE insulation sliced from 220 kV rated cable was diagnosed by partial discharge and dielectrometry measurements and optical observation. The effects of aging by rate of rise in electrical stress and time are reported. Observed intermittent light emission and tree paths supported the theory of emission of protons due to high energy electrons
