Performance of Long Transmission Lines
CHAPTER OBJECTIVES
After reading this chapter, you should be able to:
Develop mathematical models for long transmission lines
Understand the performance analysis of long lines with the help of analytical and circle diagrams
Understand the effect of surge impedance and Ferranti effect on long lines
4.1 INTRODUCTION
It is a known fact that the resistance (R), inductance (L), capacitance (C), and conductance (G) are the parameters of overhead transmission lines distributed uniformly over the whole length of the line. The localized capacitance methods (for both short and medium lines) have already been discussed in Chapter 3, but adopting these methods to long transmission lines will result in considerable ...
