The rated voltages of a single-phase transformer are 2000 V and 200 V in its primary and secondary respectively. The shunt impedance can be modelled with a resistance of 14000 ohms in parallel with a reactance of 1100 ohm, both refer to primary side. The primary and secondary series impedances are (0.12+j 0.35) ohms and (0.0012+j 0.0035) ohms respectively. A load is connected to the secondary side of transformer, draws 810 KVA with a lagging power factor of 0.85. The load voltage is same as rated voltage, that is 200 V. ▪ Use per unit method for analysis and find the voltage on primary side in pu.

A generator supplies a motor through a Y-A transformer. The generator is connected to Y side of the transformer. A fault occurs between the motor terminals and the transformer. The symmetrical components of the subtransient current in the motor flowing toward the fault are: I =-0.8- j2.6pu I =-j2.0pu I =-j3pu From the transformer toward the Fault: I = 0.8– j0.4pu I? =-j1.0pu 1 = Opu Assume X =X,=X, for both the motor and the generator. (a) Describe the fault type and find the prefault current, if any, in line a. (b) Determine the subtransient fault current in per unit. (c) Calculate the subtransient current in each phase of the generator in per unit taking into consideration the phase shift of the Y-A transformer.
