The corona loss in a transmission line is directly proportional to the operating frequency.
PC α (f + 25)
where, PC = Corona loss
f = Operating frequency
Calculation
fdc = 0 Hz and fac = 50 Hz
\({P_{DC}\over P_{AC}}={0+25\over 50+25}\)
\({P_{DC}}={1\over 3}P_{AC}\)
Hence, the corona loss in DC transmission is less than AC.
