Abstract
The onset voltage of negative corona on the discharge wire in wire-duct filters is calculated based on the criterion for the recurrence of negative corona (Trichel) pulses. The negative corona pulse corresponds to one electron avalanche followed by its successors in the ionization-zone surrounding the wire. The growth of avalanches and their successors depends on the electric field and the pressure. With gas flow in the filter, the pressure is different from the atmospheric value with a subsequent change of the onset voltage. The onset voltage is determined at different value of gas flow velocity. The obtained results are discussed in the light of gas discharge physics.
