Advantages and Limitations of high voltage transmission line:
The choice of transmission systems and rated voltages for a transmission line is made
from HV AC (upto 220 kV) EHV AC (400 kV – 750 kV) UHVAC (above 760 kV AC)
depending upon technical and economic consideration.
Advantages :
- High power transferability of AC lines P  V2. .
- Line losses decrease with increase of transmission voltage and improvement of
power factor for same power transfer.
- Bulk power transfer from large group of generating stations upto main
transmission network.
