A 3-phase generator (30 MVA, 13.8 KV, 0.15) supplies two motors (rated at 20 MVA, 12.8 KV, 20%, and 10 MVA, 12.8 KV, 20%, respectively) through a step-up transformer - transmission line - step- down transformer arrangement. The 3-phase transformers are rated at 35 MVA, 13.2 KV-A/115 KV-Y with 10 % leakage reactance. The line reactance is 80 ohms. Draw the equivalent per unit reactance diagram by selecting 30 MVA, 13.8 KV in the generator circuit. Also, calculate the current supplied by the source and the currents of each motor

10. A three-phase transformer consists of a bank of single-phase transformers connected to form a Dd0 connection. A fault on one of the transformers causes it to be removed from the circuit, and the remaining two transformers are connected in an open-delta (V-V) connection. Show that the capacity of the open-delta connected transformers is 58% of the delta-connected transformers.
The single line diagram of a power system is shown in Figure Q2.1 including generator and transformer winding connection and earthing details. The parameters for this system have been calculated on a common 100 MVA base and are given in Table Q2.1. All resistances and shunt susceptances are neglected. This system experiences a single line to ground fault at a point F on line L1. The point F is at a distance d from Bus 4 along the line L1. The total length ?? of the line L1 is 50 km.
