Which of the following is NOT one of the reason EHV (Extra high voltage) lines are preferred?
1
The installation cost of transmission line per kilometer decreases as the volume of
conductor decreases, and hence the cost of line supports reduces.
conductor decreases, and hence the cost of line supports reduces.
2
There is an increase in flexibility as it is directly proportional to volume of conductor.
3
It improves the performance of transmission lines.
4
There is a possibility of interconnecting power systems for the economical operation
of power systems.
