ELEN 3441 – Fundamentals of Power Engineering Spring 2011 Page | 2 c) At 50 km length, we can treat this transmission line as a “short” line and ignore the effects of the shunt admittance. The corresponding equivalent circuit is shown in Figure 7-1 below. Figure 7-1 The transmission line is supplying a voltage of 8 kV at the load, so the magnitude of the current flowing to the load is Assuming that the voltage at the load is arbitrarily assigned to be at 0° phase, and the power factor of the load is 0.9 lagging, the phasor current flowing to the load is I = 100 25.8° A. The voltage at the sending end of the transmission line is then d) The complex output power from the transmission line is
