Q1. A three phase interconnector has resistance per conductor of 4 22 per phase and inductive reactance of X 12 per phase, where X = Student 1's ID / 1,000,000 (92). The sending end voltage is set at 33 kV, 50 Hz. The load is adjusted such that the receiving end voltage is also 33 kV. Find the efficiency of the interconnector as a function of the phase angle difference between the sending and receiving end...

Question: A three-phase, 60-Hz, completely transposed transmission line has a length of 100-km and has a series impedance per phase of (0.25+j0.85) ohms/mile and shunt admittance of 5.0*10^-5 Siemens/mile. The transmission line delivers 150 MW at 0.85 lagging power factor to a load connnected to its receiving end. The line-to-line voltage at the receiving end is 138-kV. Note: The Medium Length Line method should be used since it is used for distances between 50 miles to 150 miles. Determine the...
