A. An open circuit test is conducted at the receiving end of a 500 kV, 60 Hz, three phase line, (Ir = 0), with the receiving end voltage maintained at 500 kV (line-to-line value). The sending end voltage is found to be 450 kV (line-to-line value) and leads the receiving end voltage by 1.3°. The sending end active power input to the line is 5.18 MW at 0.021-power factor leading. Find the line parameters A, B, and C.

B. Suppose that the load at the receiving end of the line of part A is 500 MVA at nominal voltage, and lagging power factor of 0.8 at rated voltage. Determine the sending end voltage, current, active and reactive power and power factor.
