Electrical Engineering

A 3-Phase, 60 HZ transmission line has the followingparameters:

L= 2.563 x 10^(-3) H/mi

R= 0.25 Ohms/mi

Y= 5 x 10^(3) S/mi

The line is 200 mi long and it delivers 150 MW at 220 kV andunity power factor to a substation at its receiving end.

Find the efficiency and voltage regulation of the transmissionline.
