Abstract |
The article discusses the investigation of the characteristics of a single negative corona discharge tuft and how it interacts with another tuft when forced to do so. (Used during the investigation was a new analytical method developed to calculate the main electrical characteristics for a wire-plate geometry in which the wire is contaminated with dust and excited with a negative voltage.) Results were used to develop a complete analytical solution. The analysis identified a significant region of corona at voltages well below the peak critical voltage, Vc, beginning at the tuft onset voltage, Vt = 0.6 Vc. The method was also used to calculate the maximum current density under each tuft discharge and to make a reasonable estimate of the current distribution pattern on the plate and the number of tuft discharges per unit length of wire.
