Abstract
The present article is dedicated on researches of nonequilibrium electrical discharges influence on al- ternating voltage on solid dielectrics properties and theirs break-down mechanisms after influence of the short-time high voltage impulses. Is considered an adhesion and surface energy increase mechanisms on in- terface of components in compound materials. It is shown an influence of the high voltage nanosecond im- pulses on solid dielectrics structure and properties. Is presented to quantitative connection between the process electrical parameters, the dielectrics properties and the space-time characteristics of the impulse dis- charge.
