Abstract

Planar LDPE and XLPE samples were conditioned by holding in short circuit for 48 hrs. at 40oC under rotary pump pressure, and space charge accumulation in these samples under DC fields of 20 kV/mm was then compared with the corresponding accumulation in unconditioned samples.The test results were obtained by utilizing two different test methods. These were the laser induced pressure pulse (LIPP) method and the pulsed electroacoustic (PEA) method. The thickness of the test samples was 1.80mm. Calibration of the measuring systems was performed at field strengths below that required for charge injection from the electrodes.The two test methods have given comparable test results. It has been found that the conditioning did not appear to make any consistent difference to the space charge distribution patterns or densities.
