Discharge of bushes


Discharge of bushes Sharpening - a type of electric shock that occurs in the air, resulting from impact ionization near the electrode blade. This discharge takes the form of a bundle of luminous streaks that appear to float freely from the blade. This phenomenon is an indirect effect between a corona discharge and an electric spark.

Streaks do not go all the way between the electrodes in this case, but they break in the air. Around the electrode, the air becomes highly ionized because of its high density of electromagnetic field. The formation of such discharges is dependent, among others. from voltage, clamp polarity and blade shape and length. With bushes we are dealing almost with all types of discharges from insulators. Electrons thickened on the edge of the cathode externally, while the blade is an anode, and then the cathode is formed in the gas space - the delicate paths of electrons emerge into the metal electrode.
