less...

Answer / bala

ac more no corono loss in dc

Answer / w.v.jahnavi

corona loss is less in dc when compared to ac. corona loss
is more in case of ac. because it is more predominant in
extra high voltage transmission lines.

Answer / manish

corona loss p
= .00241[(f+25)/$]*[root of (r/d)]*square of[Vp-Vo]


f= supply frequency
$= air density correction factor
Vp = operating voltage
Vo= critical disprutive voltage
r= radius of conductor
d= distance of separation for fine weather

now for dc f=0 then a certain power loss by corona but less then ac corona loss.
