6.3. A 50 Hz, three phase, 275 kV, 400 km long transmission line has resistance 0.035 O/km, inductance 1 mH/km and capacitance 0.01 µF/km. If the line is supplied at 275 kV, find out the MVA rating of a shunt reactor that would be required to maintain 275 kV at the receiving end, when the line is delivering no load. Use nominal IT method. Ans. 47.56 MVAR (lagging)

Question
6.3. A 50 Hz, three phase, 275 kV, 400 km long transmission line has resistance 0.035 0/km, inductance
1 mH/km and capacitance 0.01 uF/km. If the line is supplied at 275 kV, find out the MVA rating of
a shunt reactor that would be required to maintain 275 kV at the receiving end, when the line is
delivering no load. Use nominal II method.
Ans. 47,56 MVAR (lagging)
