Partial Discharge

 

an electrical discharge that occurs in gaseous inclusions within electrical insulation or over contaminated or damp sections of the surface of such insulation. Partial discharges cause solid insulation to age or deteriorate. To avoid the occurrence of partial discharges, materials used as insulation are subjected to special treatment, such as vacuum drying or the impregnation of voids with an electrically strong dielectric. In addition, whenever possible, the surface of insulation is kept free of contamination and moisture.

the light emission from the tip of the partial discharge is stronger than the stem ,two regions can be identified : zone I , bright and well demarcated, fits to the discharge intermediate between glow and arc used in the model ; zone II blurred and less luminous could be in connection with a space charge ejecting forward the tip of the discharge.
