A transmission line that has a resistance per unit length of 4.30 x 104 0 /m is to be used to transmit 5.00 MW over 400 miles (6.44 x 105
m). The output voltage of the generator is 4.50 kV.
(a) What is the line loss if a transformer is used to step up the voltage to 600 kV?
7.69E-3
Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.
kW
(b) What fraction of the input power is lost to the line under these circumstances?
loss/P = 1111.11
