Abstract

The results of study of the tree-inception process in low-density polyethylene in the needle-plane configuration under AC voltage are represented in this paper. The tree inception was studied in visible, UV, and IR spectra with simultaneous monitoring the partial discharge (PD) parameters. It was established that the tree inception is accompanied by the radiation in visible and UV spectra and by the local temperature rise on the sample surface by a factor of 1.5...2 irrespective of the experimental conditions such as the applied voltage, the needle up radius and interelectrode distance. It was found that between the temperature-temporal parameters and PD-parameters of the tree-inception process exists the correlation. It was shown that a diagnostics of the tree inception is possible by means of measurements of the local temperature rise on the dielectric surface and partial discharge parameters.
