Abstract
A mathematical model of the dynamics of temperature, electric field strength, and charge density in thermal dielectric breakdown is examined. The characteristics of the evolution of a thermal instability initiated by a local temperature disturbance are studied by numerical modeling. The conditions of initiation and growth of an electrothermal structure resulting in the formation of a highly conductive channel and shunting of the dielectrics current are identified.
