Power System Fault Analysis of The Nigerian 330kV Transmission Grid is a study of the determination of the appropriate circuit breaker. Relevant data were sourced from NCC, Osogbo and a digital computer fault analysis program was applied. The circuit breakers considered are SF6, Air, Oil and Vacuum and the designed criteria employed in the use of multi-criteria analysis are Cost, reliability, Flexibility and Environmental Impact. The Multi-Criteria Analysis (MCA) approach is an improvement over the traditional approach for calculating the symmetrical fault current at a system location and then selects a circuit breaker with a symmetrical interrupting capability equal to or above the calculated current. In the MCA approach, user preferences which take into account the design criteria were not ignored, as a result, a logical and rational approach has been developed for the Nigerian 330kV power system network which meets the input specifications and responds to user preference and concerns of power system operators.
