last two digits of student number are 10 Q.3 A single-phase power system is shown in Figure. The power source feeds a load through a transmission line and a IXY (kVA), 20kV/3.8kV transformer. The transformer's series impedance is shown as referred to the LV side. The source voltage is v:(t) = 2Xsin(3141) kV, which delivers 120 kVA at 0.95 power factor lagging to the system. Determine, a. actual voltage drop in the transmission line, (5 marks) b. actual voltage drop...
