Please question 10 6. A single phase overhead transmission line delivers 1100 KW at 33 KV at 0.8 p.f.lagging. The total resistance and inductive reactance of the line are 10 2 and 15respectively. Determine: i) sending end voltage ii) sending end power factor and iii)transmission efficiency.7. An overhead 3- phase transmission line delivers 5000 KW at 22 kV at 0.8 p.f. lagging.The resistance and reactance of each conductor are 4 and 6 respectively.Determine i) sending end voltage ii) percentage regulation and iii) transmissionefficiency.8. A medium single phase transmission line 100km long has resistance/km 0.259,reactance/km 0.892, susceptance/km 14 × 10-6 siemen and receiving end line voltage66,000V. Assuming that the total capacitance of the line is localized at the receivingend alone, determine i) the sending end current, ii) sending end voltage, iii) regulation,iv) supply power factor. The line is delivering 15000 kW at 0.8 power factor lagging.9. A 3-phase, 50Hz overhead transmission line 100km long has resistance/km/phase 0.12, inductive reactance/km/phase 0.2 , capacitive susceptance/km/phase 0.04 × 10-4siemen. determine i) the sending end current, ii) sending end voltage, iii) sending endpower factor and iv) transmission efficiency when supplying a balance load of 10000kW at 66 kV, p.f. 0.8 lagging using nominal T method.10. A 100km long, 3-phase, 50Hz overhead transmission line has resistance/km/phase0.1, reactance/km/phase 0.52, suceptance/km/phase 10 × 10-6 S. If the linesupplies load of 20 MW at 0.9 p.f. lagging at 66 kV at the receiving end, determine bynominal method i) sending end power factor ii) regulation and iii) transmissionefficiency
