Abstract

The effects of electrode materials on space charge formation in LDPE have been experimentally investigated using the PEA technique. Common electrode materials used in either the laboratory or power cable industry were selected (i.e. aluminium, gold and carbon loaded XLPE) and space charge accumulation after the application of high electric stresses was monitored. Experimental results demonstrated that charge injection processes take place in all cases once the applied stress has exceeded a threshold. However the amount of charge, and polarity of the dominant injected charges showed a significant dependence on the electrode materials (under the same applied electric stress).
