Observation of Light Output from Corona Discharge on a High Voltage Wire Conductor Using the CT Technique

Laser‐induced burst corona and streamer corona for a positive DC nonuniform field gap in N2/NO mixtures

“…The space charge field whose ionization area is ignored is the same as in the calculation of the stationary ion flow field, in which the hypothesis of Deutsch is also utilized, that is, the electric field on the tip of the rod electrode is kept at the corona onset field and the space charge does not influence the direction of the electric field but influences its magnitude [10]. At this time, if the space charge density at the tip of the rod electrode is fixed, the distribution of space charge field on the discharge gap and the applied voltage (obtained as the integral of the electric field) can be derived by numerical analysis.…”
