Engineering

The following information is available for a single-circuit, three-phase, 345-kV, 360 mega volt amperes (MVA) transmission line:

A. Calculate the line's inductive reactance in ohms per mile per phase.

B. Calculate the capacitive reactance including earth effects in ohm miles per phase.

C. Calculate the exact A and B parameters of the line.

D. Find the voltage at the sending end of the line if normal rating power at 0.9 PF is delivered at 345-kV at the receiving end. Use the exact formulation.

E. Repeat (d) using the short-line approximation. Find the error involved in computing the magnitude of the sending-end voltage between this method and the exact one.
