The intention of this paper is to examine the transient stability of the power system when a symmetrical three phase fault is created at bus by using E-TAP software. Transient stability is the ability of a machine to run at synchronous speed even focused to large disturbances. At this juncture the transient stability analysis is carried out for 6 bus system. The enrichment in stability and the power oscillation is damped out when the fault is cleared within time. The fault is created at bus 4 for 0.3 second and the clear fault time is 0.5 second. If the fault is not cleared within the time the generator losses its synchronism that is the generator goes out of step and produces power oscillations in the output. In order to diminish the power oscillations and bring the system again to stable critical clearing time is used. After the fault is cleared, the system oscillations are damped simultaneously the generator runs in synchronism.
