Abstract

This paper reports on space charge in XLPE planar samples of approximately 220 ?m thick subjected to dc 30 kV/mm and 1 Hz, 10 Hz and 50 Hz ac 30 kVpk/mm conditions for 24 hours. Measurement of space charge was carried out using the pulsed electroacoustic (PEA) technique. In addition, experiments with higher applied electric stress of 60 kVpk/mm at 50 Hz ac condition were also conducted over an ageing period of 24 hours. In order to investigate the effect degassing on space charge distribution of samples under ac stress, both as-received and degassed were used in this study.
