A three-phase transmission line has parameters Xc-6 k 2, R-3.25 2 and X₁-25 0, and delivers 300 MW to a load with both ends of the line at 230 kV. Draw a pi equivalent per-phase circuit of the line. On a per-phase basis, calculate the active power delivered to the load, the reactive power of the line and the active power delivered by the source. Based on these calculations can the equivalent circuit be simplified further?
