phase and three phase, single and double circuit lines, concept of GMR & GMD, symmetrical and
asymmetrical conductor configuration with and without transposition, Numerical Problems.
Calculation of capacitance for 2 wire and 3 wire systems, effect of ground on capacitance, capacitance
calculations for symmetrical and asymmetrical single and three phase, single and double circuit lines,
Numerical Problems.


UNIT-II 
Performance of Short and Medium Length Transmission Lines
Classification of Transmission Lines - Short, medium and long line and their model representations -
Nominal-T, Nominal-Pie and A, B, C, D Constants for symmetrical & Asymmetrical Networks, Numerical
Problems.
Mathematical Solutions to estimate regulation and efficiency of all types of lines - Numerical Problems.


UNIT-III 
Performance of Long Transmission Lines
Long Transmission Line-Rigorous Solution, evaluation of A,B,C,D Constants, Interpretation of the Long
Line Equations, Incident, Reflected and Refracted Waves -Surge Impedance and SIL of Long Lines,
