Corona loss can be reduced by the use of hollow conductor, because
the current density is reduced
The eddy
current in the conductor is eliminated
For a given cross section, the radius of the conductor is increased
of better
ventilation in the conductor
For a given cross section, the radius of the conductor is increased
Corona power
loss - Corona loss is the other major
of power loss in transmission lines essentially corona loss is caused by ionization of air molecules the transmission line conductor. Corona loss can be reduced by the use of hollow conductor.
Because for a
given cross section, the radius of the
conductor is increased.
The hollow conductor increases the effective diameter without using anyextra material.
