A 3-Phase, 60 HZ transmission line has the following parameters:
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 and unity power factor to a substation at its receiving end.
Find the efficiency and voltage regulation of the transmission line.
