A 3-ph transmission line has a total length of 200 km. This transmission line has a resistance of 0.16 Ohm per phase per km, an inductive reactance of 0.25 Ohm per phase per km, and a shunt admittance of 1.6 micro Siemens per phase per km. When this transmission line is supplying a load with 20 MW at (V) kV and 0.8 lagging power factor where V = 100 + VV and VV is the last two digits from right of your registration number. Using long length representation, find: 1- The voltage drop across this T.L. Suggest verifying your suggestion a way to decreasethis voltage drop to 50%. 2- The transmission line efficiency. 3- The loadability of transmission line (approximate calculations). Suggest verifying your suggestion a way to increase this loadability to three times. 4- The propagation velocity and the corresponding wave length.
