Abstract :
To investigate the relationship between insulation and electrode materials in the formation of space charge, various combinations of insulation-grade polyetheylene and different types of electrodes were used in experiments involving the pulsed electroacoustic method. It was found that cross-linked polyethylene and low-density polyethylene showed a hetero-space-charge distribution whereas high-density polyethylene showed no space charge formation at room temperature. The use of semiconductive materials for the electrode led to the formation of a positively charged region near the electrode. This accumulation of positive charge did not occur for a Au/carbon black electrode. In addition, attempts were made to observe the time dependence of the charge distribution in specimens
