Abstract
PPLP is a prominent insulating material with high dielectric breakdown strength and low dielectric loss, which has been in practical use for OF cables in EHV/UHV transmission system. Neverthless, the dielectric breakdown mechanism of oil-impregnated PPLP system has not been cleared sufficiently.<br>This paper demonstrates that the relationship between the ac partial discharge properties and the dielectric breakdown mechanism of an oil-impregnated PPLP can be clarified by using a needle-plate electrod system. In this paper, we came to the conclusion that the ac partial discharge properties of an oil-impregnated PPLP can be roughly devided into five types which are caused by the dielectric breakdown of each part in the oil-impregnated PPLP system: oil layer part, kraft paper part and PP-film part.
