Abstract :
Breakdown, or channel formation, of a polymer under transient conditions occurs in a single step and generates a conducting pass, which indicates that the electric field in the breakdown region collapses extremely rapidly. In this contribution, a new mathematical model of a breakdown channel configuration in solid dielectrics under impulse conditions is investigated. Also, this paper studies the energy to form a breakdown channel and its effect on unique and mixture dielectrics.
