Yuri,
   Corona is the ionization of air caused by high voltage.  The negative 
effect of it is that it creates ozone and NOx compounds that will attack 
plastics.  It also becomes a conductive path for electricity to follow, and 
causes losses in high voltage circuits.  It will appear as a bluish purple 
light around metal objects(such as capacitor plates, eg).  It is difficult to 
see if the room is lighted, but is readily visible in a dark room.
