Computational estimation of ESD conditions between a charged body and a conductor of floating potential

摘要: This paper examines the conditions in which a discharge occurs between charged body and floating conductor, air, at atmospheric pressure. The study, was primarily aimed simulating class of hazardous situations quite often met operation electronic circuits, is also interest to those involved research development electrostatic technologies for processing particulate matter: separation granular mixtures, precipitation dust, spraying powders. boundary-element method employed analysis electric field gap conductive disk potential, located above grounded plate. computations were carried out bodies various shapes sizes; some them addressed case plate covered with an insulating layer known permittivity. data on distribution represented input another program, estimated breakdown that air gap. study enabled estimation energy this type prediction related hazards.
