Description/Abstract
The electrical properties of polymeric insulation deteriorate in service, when subjected to electrical stresses over a period of years. Possible chemical changes in low-density polyethylene (LDPE) subjected to electric stresses at power frequency have therefore been investigated, using Raman microprobe spectroscopy. Although no significant specific chemical changes were detected when samples were subjected to high stresses for short periods of time, a clear increase in background fluorescence was seen in samples aged for longer periods of time. Raman spectra have also been obtained from around failure sites and compared with those obtained from unaged samples and specimens containing electrical trees.
