Abstract

The pulsed electroacoustic method was used to analyze the influence of cross-linking agent residues on the spatial charge distribution in XLPE (cross-linked polyethylene) plates. With the change of the content of residues in samples, one can determine the following. Heterocharges dominate in the charge distribution when the content of residues is high. Homocharges dominate in the charge distribution when the content of residues is low. Heterocharges and homocharges alternately dominate in the charge distribution when the content of residue is not very high and not very low, respectively. Heterocharge distribution is due to the movement of residues in the sample, and homocharge distribution is due to the injection of electrons and holes from the cathode and anode. Electron injection from the cathode is easier than hole injection from the anode
