Part C) and D) is asking for Xthev, Ifault, and voltages at Bus
4 and Bus 5. Thanks.
PROBLEM 5 a Discuss the consequences of short circuit faults on electric power systems [5 Points] b Protective schemes are routinely used for electric power transformers. Name at least three different types of transformer protective schemes (by function) and explain briefly their principles of operation. [5 Points] Consider the system shown in the single-line diagram of Figure (4.) All reactances are shown in per unit to the same base. Assume that the voltage at both sources is 1 p.u. c Find the fault current due to a bolted- three-phase short circuit in the middle of line B. [5 Points] d Find the voltages at buses 4 and 5 under the fault conditions of part c above [10 Points] 2 0.2 p.u 0.1 P.U. 0.2 p.u Line A 0.1 P.U. ???? - Line B 003 800 0.1 P.U. - circuit breaker a.c. generator transformer 0.1 P.U. 0.2 p.u +380 0.2 p.u. 0.2 p.u.
