Consequent effects on the real and reactive power losses, Electrical Engineering

Assignment Help:

Q. Consider an upgrade of a three-phase transmission system in which the operating line-to-line voltage is doubled, and the phase or line currents are reduced to one-half the previous value, for the same level of apparent power transfer. Discuss the consequent effects on the real and reactive power losses, and on the voltage drop across the series impedance of the transmission system.
