3.0‐ns surface discharge development

摘要: The nanosecond time‐scale developing mechanisms of positive and negative corona streamers on the insulation surface are investigated using a square pulse generator Lichtenberg figure technique. length in air is measured at duration 3 ns, an applied voltage 7–20 kV, gas pressure 150–760 Torr. results compared with those obtained time range 5–920 ns. ratio certain that atmospheric becomes constant value irrespective magnitude voltage, it increases as reduced. lag streamer inception decreasing pressure. for 20 kV 0.1 ns 0.35 150 Torr, while same 0.55 ...
