The Mechanism of the Positive Point-to-Plane Corona in Air at Atmospheric Pressure Attention is called to the fluctuating character of the current in the positive point-to-plane corona in air at atmospheric pressure. It is shown that in the self-sustaining corona the current is due to a larg...
The paper presents investigations of self-pulsing discharges in atmospheric pressure air pre-heated to 300–1000 K. Despite using a direct-current power supply, two self-pulsing discharge regimes, a repetitive transient spark (TS) and a repetitive streamer (RS) were generated. The pulse repetition...
