Electrical breakdown in air

WebPartial electrical breakdown of the air causes the "fresh air" smell of ozone during thunderstorms or around high-voltage equipment. Although air is normally an excellent insulator, when stressed by a sufficiently high voltage (an electric field strength of about 30 x 10 5 V / m [1]), air can begin to break down, becoming partially conductive. WebOct 20, 2024 · Investigation of memory effects in air at 0.7 mbar pressure in the presence of vacuum electrical breakdown mechanism has been performed in this paper.
