Abstract
This paper presents experimental results of space charge distribution in cross-linked polyethylene by a pulsed electroacoustic method. The influence of crosslinking agent residues on space charge distribution in XLPE which contained different content of residues is studied to understand the transport and injection of charges under DC voltage. Homocharge distribution is dominant when the content of residues is low whereas heterocharge distribution is dominant when the content of residues is high. A new data display method of a three-dimensional color plot is proposed to display all measurement data on one plot by which the time dependence of space charge distribution can be understood easily and conveniently.
