In this paper,the voltage-current(Ⅴ-Ⅰ)characteristics of a pin-plate system with four types of collection plate configurations are studied experimentally.The collection plates consider a single metal plate,a metal plate with a fly ash cake layer,a metal plate with a clean filter media and a metal plate with a dirty filter media.The results show that the clean filter media has no obvious effect on the Ⅴ-Ⅰ characteristics.But the dirty filter media reduces the current density because of its high resistance.The thick fly ash cake layer increase current density because of the anti-corona effect but the increment is not very obvious.
