Correct Answer - Option 1 : 20 kV to 100 kV
Transmission lines are classified based on three criteria.
a) Length of transmission line
b) Operating voltage
c) Effect of capacitance
The table below summaries the classification of transmission lines.

Transmission Lines
|
Length of transmission line
|
Operating voltage
|
Effect of capacitance
|
|
Short transmission line
|
(0 - 80) km
|
(0 - 20) kV
|
'C' is not considered
|
|
Medium transmission line
|
(80 - 200) km
|
(20 - 100) kV
|
'C' is lumped.
|
|
Long transmission line
|
(> 200) km
|
(> 100) kV
|
'C' is distributed
