Transmission line models
Unlike the electric machines studied so far, transmission lines are characterized by their distributed parameters: distributed resistance, inductance, and capacitance.
The distributed series and shunt elements of the transmission line make it harder to model. Such parameters may be approximated by many small discrete resistors, capacitors, and inductors.
Classification of Overhead Lines
Short transmission lines
Medium transmission lines
Long transmission lines
