Abstract

Partial discharge (PD) characteristics of chemically modified polyethylenes were investigated. The chemical modification of polyethylene was made by grafting acrylic acid (AA) or n-butyl acrylate (nBA) onto polyethylene chains. It was found that the partial discharging activities in AA or nBA grafted polyethylenes were considerably suppressed, which was attributed that the change of molecular structure in polyethylene changes the environment in voids formed by the micro-breakdown in the vicinity of needle tip. It was also found that AA was more effective than nBA in preventing partial discharge of polyethylene.
