Key Modes of Ignition and Maintenance of Corona Discharge in Air

Theoretical and experimental studies of various modes corona discharge operation in atmospheric pressure air are presented this short review. The original results modeling negative discharges presented, taking into account the non-stationary plasma-chemical kinetics charged particles plasma. space–time evolution needle-to-plane geometry is investigated analyzed. Several stages development revealed from moment initiation a low-negative current to quasi-stationary mode glow discharge. Experimental data authors presented. Modern technology diagnostic equipment with wide variation main parameters (the shape polarity applied voltage, type gap, etc.) was used. measurement optical characteristics plasma carried out high spatial resolution. Corona pulse profiles at have been recorded subnanosecond time With positive pin electrode transition spherical streamer initiating cylindrical shown. author’s rigorously evaluated through critical comparison findings other research groups.
