Question
3-) Three-phase, 100 km long unit length and serial impedance
per phase is 0,125 + j0.34 2/km. The effect of the shunt
admittance and leakage conductivity of the line is neglected. If
the line-in voltage is 154 kV and the voltmeter on the receiver
side, a voltage of 10% lower than the line-in voltage is read. In
this operating situation, if the value of the reagent power
absorbed at the end of the line is zero,
a.) The value of the current drawn at the end of the line,
b.) The value of the active power absorbed by the end of the
line,
c.) Calculate the value of the active power sent from the line
to the end of the line and the efficiency of the line.
Note: The calculations will use 3 digits after the comma.
