Pulsed Laser Control and Space Charge Electric Field for Positive DC-Corona Discharges in Atmospheric Air

摘要

For a rod-plane discharge gap, the mechanisms of DC sparkover is studied by the discharge luminent process, the spectroscopic image processing and the measured results of space charge field. It is verified that the pulse laser triggering method is effective to the measurement of space charge field and the observation of discharge luminous transition for glow corona discharges.
