Consider a 3ϕ, 345 kV, 60 HZ, balanced transmission line with 3- ACSR Eagle type conductors/phase. The phases are placed on a horizontal plane with phase spacing of 30 feet, 30 feet, and 60 feet, and conductor separation (in each phase) is 18 inches. Assume a 500C temperature and and a) Calculate the series impedance and shunt admittance of the line for one-mile length, b) Calculate the MVA rating of this line (use thermal limit) c) Calculate the approximate charging current and approximate reactive power supplied to the rest of the system by this line for 100 miles length d) Calculate, propagation constant (for 1 mile length), and characteristic impedance of this line 2. Consider the line described in Problem 1 (with 100 Mile length). If this line is said to be supplying 240MW at 340KV, and at a power factor on 0.85 lagging, calculate the efficiency and % voltage regulation of the line. Use medium-length-line model
