Give all your answers correct to 5 decimal places. Answers requiring complex numbers should be given in polar form A 150 MVA three-phase transmission line is 45 Km long, the parameters of the line (per-kilometer) are r = 0.16 Ohms and x = 0.74 ohms. The voltage at the receiving end of the transmission line is 220 kV. Calculate the series impedance of the line: Your response 34.06948782 Auto graded Grade: 8/8.0 Correct response 34.069488:0.01 Correct response 77.799597+0.01 Your response 77.79953127 Auto graded Grade: 7/7.0 Degrees Calculate the phase "a" line current if the line supplies rated voltage and apparent power at a power factor of 0.8 lagging: Your response 393.64791081 Auto graded Grade: 5/5.0 Correct response 393.647911:0.1 Correct response -36.8698980.01 Your response -36.86989765 Auto graded Grade: 5/5.0 Degrees Calculate the sending end phase voltage if the line supplies rated voltage and apparent power at a power factor of 0.8 lagging: Your response 137434.754 137,430.70424100 Auto graded Grade: 10/10.0 VL Correct response
