A74kv (line-line) three phase short transmission line is 24km long. the line has a per-phase series impedance of 0.1+0.5j ω/km. shunt capacitors are installed at the receiving end to improve the line performance. the line delivers 100mva, 0.8 lagging power factor at 64kv (line-line). question 1 determine the sending end voltage angle δ in degrees when the sending end voltage is 74kv. assume the receiving end voltage angle is 0 deg.
