#1. A 3-phase, 60-Hz transmission line is 50 km long and has r =0.20 Ohms/km and x =0.50 Ohms/km. The load at the receiving end of the line is 2.5 MW at a power factor of 0.9 leading. (i)Compute the impedance of the line, Zine * at the lad take the lad vellage as 33KV llne to line. Van - reference. (ii)Find the sending end current, I, (iii) What is the sending end voltage, V,? (iv)What is the real power, P and the reactive power Q at the sending end? (v) Calculate the V.R. the voltage regulation of the line. (vi) What is the efficiency, n, of the transmission line?
