A three-phase transmission line, 10 km long delivers a load of 5000 kW at 11 kV and 0.8 pf lagging at the receiving end. The resistance of the line per km per phase is 0.1 Q and the reactance per phase per km is 0.2 2. Solve for the sending end voltage of the line, total current and voltage regulation of the line. Present also the transmission line modeling.

Question
A three-phase transmission line, 10 km long delivers a load of 5000 kW at 11 kV and 0.8 pf lagging at
the receiving end. The resistance of the line per km per phase is 0.1 2 and the reactance per phase per
km is 0.2 2. Solve for the sending end voltage of the line, total current and voltage regulation of the
line. Present also the transmission line modeling.
