To increase the transmission capability of a high voltage long line

A. The resistance can be increased
B. The resistance can be decreased
C. The Series Reactance can be reduced
D. Shunt admittance can be reduced

Answer: C. The Series Reactance can be reduced

Explanation:

Series capacitors: 

  • Series capacitors are used to compensate the inductance of the transmission line. 
  • They will increase the transmission capacity and the stability of the line. 
  • These are also used to share the load between parallel lines.
  • Series capacitor is used in a transmission line to compensate the voltage Drop.
  • In series compensation, the FACTS is connected in series with the power system. 
  • It works as a controllable voltage source. 
  • Series inductance occurs in long transmission lines, and when a large current flows this causes a large voltage drop. 
  • To compensate, series capacitors are connected, decreasing the effect of the inductance.
