A large power plant generates electricity at 12.0 kV. Its old transformer once converted the voltage to 385 kV. The secondary of this transformer is being replaced so that its output can be 500 kV for more efficient cross-country transmission on upgraded transmission lines.
(a) What is the ratio of turns in the new secondary compared with turns in the old secondary
(b) What is the ratio of new current output to old output (at 425 kV) for the same power?
(c) If the upgraded transmission lines have the same resistance, what is the ratio of new line power loss to old?
