For a rod -plane discharge gap, the mechanism 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.
A decrease in sparkover voltage with pulse laser irradiation, is decided by the transition from glow corona to streamer corona and the electric field for the heating of transient filamentary glow-channel.
