A 3 phase 50Hz overhead line has the following constants: R/phase=2ohms; Xl/phase=10ohms and Y/phase=4x10^-4 siemens. The line is supplying a balanced load of 24000 KVA, 0.8 pf lagging at 66KV. Compute for the sending end voltage, sending end current and efficiency of the line using:
a.Nominal T Method
b.Nominal pi Method
c.Rigorous Method
