Abstract
Fault studies play a significant role in the power system security for the supply and generation of electrical energy to end-users. This research work focuses on the analysis and simulation of 3 kV" fault phenomenon to determine the voltage magnitude and fault cwrent magnitude in the test system. The test system is the Nigeria 28-bus, 330 kV Transmission System. The 28-bus system is simulated using 1.1ATLAB-based programme and the maximwn cment magnitude obtained is used to determine an appropriate value of the circuit breaker rating for all the lines in the 330 kV power system. This research therefore, suggests the level of protection to be applied on Nigeria 330 kV power lines with the aim of improving system security as the information gained from this study helps in the setting of relay. The study revealed the abnormally high magnitude of cwrent that flows through the power line to the point of fault and recorded the highest value of 6.4376 kA (36.796 pu) through tbe line 4-3 (Jebba GS-Jebba IS) when Jebba GS is faulted
