Construct a receiving-end power-circle diagram similar to Fig. 6. 11 for the line of Prob. 6.12 Locate the point corresponding to the load of Prob. 6.12, and locate the center of circles for various values of |Vs| if |VR| = 220 kV. Draw the circle passing through the load point. From the measured radius of the latter circle determine Will and compare this value with the values calculated for Problem. 6.12.
Prob. 6.12
A 60-Hz three-phase transmission line is 175 mi long. It has a total series
