Abstract
The results of study of the tree-inception and growth in PMMA in visible and IR spectra and PD-parameters are presented in this paper. It is established that tree-inception and growth is accompanied by both a local temperature drop on the sample surface and essential increase in the PD-activity. The growth of trees has a stepwise nature with time. The tree-inception and growth is accompanied by a local increase in a temperature drop at the surface of dielectric by a factor of 1.5...2. Correlation between the PD-activity and a temperature drop at the surface of dielectric is found.
