campared to ac, in dc corona loss is..

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.
