A transmission line that has a resistance per unit length of4.5*10^-4 ohms/meter is to be used to transmit 5.00MW over 400miles (6.44 *10^5m). The output voltage of the generator is4.50kV(rms).
(a) What is the line loss if a transformer is used to step upthe voltage to 500kV (rms)?
(b) WHat fraction of the input power is lost to the line underthese circumstances?
(c) What difficulties would be encountered on attempting totransmit the 5.00MW at the generator voltage of 4.5kV (rms)?
