Corona discharge - Wikipedia
A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. It represents a local region where the air (or other fluid) has undergone electrical breakdown and become conductive, allowing charge to continuously leak off the conductor into the air.
Corona Discharge: What is the Corona Effect? - Electrical4U
2024年5月2日 · Corona Discharge Definition: Corona discharge is defined as an electrical phenomenon where a high-voltage conductor ionizes the surrounding air, visible as a violet glow and audible as a hissing sound.
Corona Discharge - an overview | ScienceDirect Topics
A corona discharge is an electrical discharge brought on by the ionization of a fluid surrounding a conductor that is electrically charged. From: Applied Energy, 2016
Corona & Gap Discharges Corona is an electrical discharge (i.e. partial breakdown of air insulation) occurring in the high electric field region, generally in the vicinity of conducting surfaces, but sometimes also near insulating surfaces, due to ionization processes in the air. Complete electrical breakdown of air insulation between two
Corona discharges: fundamentals and diagnostics - ResearchGate
2001年1月1日 · This paper is aimed at the characterization of the corona discharge generated from a high-voltage wire electrode facing a grounded plate in the presence of dielectric materials of different...
The Nature and Manifestation of Corona Discharge - Hubbell …
2018年12月4日 · In physics, the glow and audible event occurring when an insulator is exposed to excessive voltages is called a corona. It may also be known in the electric industry as “corona discharge,” “plume discharge,” “brush discharge” or “glow discharge.”
Corona Discharge Characteristics under Variable Frequency and …
Atmospheric pressure, applied voltage, supply frequency and geometry are dominant variables to determine corona discharge inception and extinction levels. It is worth noting that reliability and safety are key points in aircraft systems.
Corona discharge processes | IEEE Journals & Magazine - IEEE …
2002年8月6日 · Corona process applications emphasize one of two aspects of the discharge: the ions produced or the energetic electrons producing the plasma. The ion identities depend on the polarity of the discharge and the characteristics of the gas mixture, specifically on the electron attaching species.
corona discharge is, by definition, a gas discharge where the geometry confines the gas ionizing processes to high-field ionization region(s) around the active electrode(s). The corona geometry
