Conclusions
The experimental results of the above investigations justify the following conclusions:
-
1.
Ionization in gas gaps (occlusions) of an intensity lower than some critical level acting on a dielectric leads to its breakdown by surface erosion.
-
2.
lonization of an intensity equal to or higher than some critical level acting on a dielectric causes physico-chemical dielectric-breakdown processes at a considerable depth from the dielectric surface experiencing the effect of ionization, leading to a sharp reduction in its service life.
