Corona is a result of the ionization of a fluid around a conductor; when referring to electrical power lines, this is the ionization of the air around the conductor. At very high voltages (200kV and greater), this can become very significant, and can cause the deteriation of the conductor, or any conducting surface near the conductor, so special care is taken to mitigate it (such as using corona rings and bundled conductors). The ionization is a result of the buildup of electrons. Corona rings and bundled conductors provide a larger surface area for the electrons to "sit on".

What are the Advantages of Corona in transmission lines?
Due to corona effect virtually conductor size is increase and therefor resistance in transmission line is decreases.so I2R losses will decreases...
What is corona power loss in transmission line hvdc?
A: Transmission lines while there is ceramic insulators providing separation to the phases will have a corona if the insulators are dirty providing small current leakage ionizing the air around it therefore corona effect.
What is corona effect in electrical?
When the distance between two conductors is more than that of the diameter and the potential difference is increased beyond the certain limit in such a way so that a glow ( seems like violet and shine ) is produced around the conductor and also noise is produced. This kind of effect called the Corona Effect in power systems. As the potential difference is increased, Corona Effect is also increased, and due to Corona Effect, Power loss in power system and disturbance in the nearer communication line is also increased.
What is the minimum voltage required to avoid corona effect?
In air at sea level, 327 V peak.

Why there is no corona in DC transmission?
Bcoz, corona effect is only possible in high voltage AC supply due to the frequency. That is, the frequency and the HT voltage causes the arc b/w 2 conductors.so , here the air is act as the arc transmitting medium.we called it as Corona. It is highly impossible in DC bcoz of no frequency.
