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...

A long, lossless, three-phase transmission line is operating with 60 Hz with a nominal voltage of 400 kV. The distance between sending and receiving sides of the line is 350 km and the line’s series inductance and shunt capacitance per length per phase are 0.92 mH/km and 0.016µF/km, respectively. If the line delivers 667.2461 MW at 400 kV with unity power factor at its receiving side, what would be the line-line voltage magnitude in the middle of the line?
