Considet a three-phase transmission line operating at the sending end voltage of 500kV. Theseries impedance is z= 0.045+j0.4Ωper phase per km and the shunt admittance is y= j4×10-6Siemens per phase per km. For the following cases, evaluate transmission matrix for shortlength, medium length and long length models, and find the receiving end voltage (per phase)at no load using all three models. What can you conclude from this exercise?
a)When the length of the transmission line is 50 km
b)When the length of the transmission line is 100 km
