Streamer Propagation in Hybrid Gas-Solid Insulation
Paper in proceeding, 2015
The influence of a solid dielectric barrier on development of an electrical discharge in air between needle and plane electrodes is analyzed by means of computer simulations. The computational model describing formation and propagation of a streamer in atmospheric air and accounting for charge transport and trapping on barrier surfaces is presented. The results of the simulations performed for 5 cm air gap containing solid barrier (plate) inserted between the needle and plane electrodes are discussed focusing on discharge dynamics and associated electric fields.
