Kufotokozera:

Mphete ya corona, yomwe imatchedwanso kuti anti-corona mphete, ndi toroid ya zinthu zochititsa chidwi, nthawi zambiri zachitsulo, zomwe zimamangiriridwa ku terminal ya zida zamphamvu kwambiri.Ntchito ya mphete ya corona ndikugawa gawo lamagetsi lamagetsi ndikutsitsa mayendedwe ake apamwamba kwambiri pansi pa malo a corona, kupewa kutulutsa kwa corona.Mphete za Corona zimagwiritsidwa ntchito pamagetsi apamwamba kwambiri otumizira magetsi ndi ma switchgear, komanso pazida zofufuzira zasayansi zomwe zimapanga ma voltages apamwamba.

Corona discharge ndi ionization ya mpweya moyandikana ndi ma conductor apamwamba kwambiri.Nthawi zina zimawonekera ngati kuwala kwa buluu wofiyira mumlengalenga pafupi ndi zida zamagetsi apamwamba.Malo amagetsi apamwamba amawonitsa mpweya, kulola kuti madzi atuluke kuchokera kwa kondakitala kupita mumlengalenga.Mu mizere ndi zida zotumizira mphamvu zamagetsi, corona imabweretsa kuwonongeka kwakukulu kwachuma.Pazida monga ma jenereta a electrostatic, majenereta a marx, ndi makanema apawayilesi akanema, kuchuluka komwe kumabwera chifukwa cha kutayikira kwa corona kumatha kuchepetsa mphamvu yamagetsi opangidwa ndi chipangizocho, ndikupangitsa kuti zisagwire ntchito.Coronas imapanganso mpweya woipa komanso wowononga wa ozoni, womwe ungayambitse kukalamba ndi kusokoneza zinthu zapafupi monga zotetezera, ndikupangitsa ngozi kwa ogwira ntchito ndi okhalamo.Pazifukwa izi kutulutsa kwa corona kumawonedwa kukhala kosayenera pazida zambiri zamagetsi.
