3. A 60Hz, single phase line transmits power to an inductive load that has a receiving voltage of 13.8KV, reactive factor of 0.6 and 5 MVA respectively. If this line has a impedance of 1+j2 ohms per conductor, Calculate the following: The voltage at the sending end (10 pts) b. The transmission line efficiency (10 pts) c. If this line is connected in parallel to a telephone wire and the conductors of the power line is labelled a and b and on the telephone wire 1 and 2 respectively. The power lines has a horizontal distance of 5m and the telephone wire is symmetrically positioned 3m below conductor 'b' with the telephone wires having 2m spacing. Determine the voltage induced on the telephone wire in V per km using the result of the current on this problem. Note that phasors la -- Ib and the neutral current is assumed zero. (10 pts)
