Mixed Problems on Topics
1. A three-phase short transmission line has a lumped impedance of 0.25+0.5j ohms. If the
load side current is 250e^j10 A, what is the real power loss in the line?
2. A three-phase medium length transmission line has lumped impedance Z = 0.25+0.5j
ohms and lumped admittance Y = j100x10^-6 S. If the load voltage is 100 kV and current is

Step 1

To find the real power loss in the line, we need to calculate the product of the load side current and the real part of the impedance. Real power loss = 250 * 0.25 = 62.5 watts. Show more…
