1. Calculate the shunt admittance of the line in siemens per km.
2. The single-phase transmission line is operating with the receiving side of the line open-circuited. The sending end voltage is 8 kV at 50 Hz. How much charging current is flowing in the line?
3. The single-phase transmission line is now supplying 8 kV to an 800 kVA, 0.9 PF lagging single-phase load.
(a) What is the sending end voltage and current of this transmission line?
(b) What is the efficiency of the transmission line under these conditions?
(c) What is the voltage regulation of the transmission line under these conditions?
