A 60-Hz, 100-km, three-phase overhead transmission line, constructed of ACSR con- ductors, has a series impedance of (0.1826 + j0.784) N/km per phase and a shunt ca- pacitive reactance-to-neutral of 185.5 × 10³/–90° N-km per phase. Using the nomi- nal a circuit for a medium-length transmission line, (a) determine the total series impedance and shunt admittance of the line. (b) Compute the voltage, the current, and the real and reactive power at the sending end if the load at the receiving end draws 200 MVA at unity power factor and at a line-to-line voltage of 230 kV. (c) Find the percent voltage regulation of the line. (Kindly do not copy-paste answer from any other source. Kindly answer as asked in the question. Kindly show detailed steps, workings and provide explanantions for your answer. If you are confused about showing detailed ste workings and providing explanations, then kindly skip the question and leave it for someone else.)
