Charging Insulating Barrier by Corona in Air in Large Coaxial System
Paper in proceeding, 2015

Results of the experimental study and computer simulations of corona charging of an insulating barrier in a large scale coaxial arrangement are reported. A computational model describing transport of charged species generated by corona and their dynamics on dielectric surfaces is presented. The measured and computed voltage-current characteristics of corona discharge are compared and discussed. It is shown that charges deposited on gas-solid dielectric interfaces reach a steady state after few cycles of the applied triangular ac voltage. The electric field induced by the surface charges modifies the field in the entire system and alter corona characteristics.
