摘要: The triode electrode system is frequently employed for accurately controlling the corona charging of insulating materials. primarily aim this paper to characterize by current-voltage and current density distribution measurements. electrostatic aspect electric field generated also numerically analyzed, using a charge simulation program. ionizing element thin Tungsten wire (diameter: 200 μm) attached cylinder 26 mm) distanced at 34 mm from its axis. wire-cylinder assembly “dual” electrode, facing grid connected well-defined potential, grounded plate (aluminum, 250 × 130 mm).The inter spacing has very significant influence on characteristics extension discharge it. experimental results obtained different geometries are interpreted in light numerical modeling field, order make some recommendations regarding design operation.
