Question
1-What is the parameters of the a transmission line?
Classify the transmission line according the length
and voltage? Draw the phaser diagram for each of
them? Explain the reason of classification? Is there a
topology could use for more than one classification?
2-A 3-phase, 50 Hz overhead transmission line, 100
km long, 110 kV between the lines at the receiving
end has the following constants :
Resistance per km per phase 0-153 Q
Inductance per km per phase = 1:21 mH
Capacitance per km per phase = 0-00958 µF
The line supplies a load of 20,000 kW at 0-9
power factor lagging. Calculate using nominal
EKrepresentation, the sending end voltage, current,
power factor, regulation and the efficiency of the line.
Neglect leakage..

3-Calculate A, B, C and D constants of a 3-phase, 50
Hz transmission line 160 km long having the following
distributed parameters :
R = 0-15 Q/km ; L = 1.2x10^(-3) H/km; C 8×10^(-9) F/
km ; G = 0
