29. sm of corona discharge Corona discharge is a current flow usually in the air from a discharge electrode which is under high voltage High voltage is a source of air ionization which creates plasma around the electrode it is ionized matter containing electrically charged particles The resulting ions carry the load to places of lower poteniial 6 Corona Camera UV 260 Operating manual If the discharge electrode which may be any object under high voltage has a proper sharpened shape then a high potential gradient is generated around this part generates which may lead to a discharge At very high voltage it may be a spark or arc if a plasma channel is created In contrast corona discharge is formed when a voltage that causes ionization is too low at the moment to create the plasma channel The discharge is invisible in daylight in total darkness rarely occurring in outdoor conditions it is hardly visible as a blue violet afterglow as most of the radiation generated is in the ultraviolet range invisible to human eye and therefore the development of UV radiation detectors causes gradual replacement of acoustic based detection methods with UV based detectors Corona discharges generate the electromagnetic spectrum in the range of 200 405 nm solar radiation also contains in addition to visible light both infra red and ultraviolet radiation Using an appropriate filter wavelength range of 240 280 nm suppress UV radiatio
