The corona
loss depends on which of the following parameters ?
Size of the
conductor
Frequency of
supply
Atmospheric
conditions
All of the above
All of the above
Corona loss
depends on the all the factors given in the options.
1. Size of
the conductors - The diameter of the conductors can be increases by either using
hollow conductors or ACSR conductors. In present practice we prefer bundled
conductors for reducing corona loss.
2. Frequency
of supply Corona power loss 
3. Atmospheric
condition – It humidity increases, more corona formation occurs.
