A. Less than 20 kV
B. More than 200 kV
C. 20 kV to 100 kV
D. 50 kV to 200 kV
Answer: C. 20 kV to 100 kV
Explanation:
Transmission lines are classified based on three criteria.
a) Length of transmission line
b) Operating voltage
c) Effect of capacitance
The table below summarizes 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 |
