Corona Losses

I guess you want us to demonstrate our mind reading capability to answer your question. I keep trying to get a picture of what your thinking, but all I get is a total blank. Wait a minute, maybe my psychic skills are working.

Go back and read your homework text again.

If you really can't get it there... use google and type in the primary portion of your question and the answer is right there on the first page.

Advantages? There are none. Corona losses are resistive power loss which is power that must be generated but cannot be metered or sold.

corona fenomena is are space between same part on the high voltage aparatures. potential feild are there make same particels reday to saparate. when media goes down particels release and made a noise and spark, if worst conditions spark is high and sparkover occure. this is make a losses high resistand and burn parts.

In terms of energy loss the corona is an unwanted effect. But due to the increased conductivity of the insulating air around e.g. an overhead transmission line the electrical field distribution around the conductor appears as if would have a much bigger diameter. Despite the losses the corona is a sort-of wanted effect for reducing the diameter of the conductor as well as optimum insulation spacing between the three phases.

Are we missing the point?

As per any number of literature, see here

corona discharge losses are so large as to offset the advantage of lower heating loss in the line conductors

In fact to avoid this the HVDCs are in use.

The only advantage of Corona, as I learnt long back was to make the lines work just below these so that the voltage spikes (eg lightning strikes) are dissipated.

Sorry, but you left the door open............

Corona losses, no big deal. Tecate or Dos Equis losses, now that is a shame!
