Abstract

This study centers on the fault analysis of 15MVA Mofor Injection Substation, which is an Injection Substation located in Warri, Delta state, Nigeriawhich gets its source from PTI transmission station. Mofor Injection substation has two outgoing feeders which are Orhuwhorun feeder and Ekete feeder. The analysis was carried out and deductions were made considering the various faults which occurred during the period of assessment and their associated fault current was calculated using symmetrical Component method of Fault analysis. Amodel of the distribution network was made using Electrical Transient Analyzer Program(ETAP); the value of real and reactive powers and voltage magnitudes in the whole network wereobserved. Thedata obtained from the injection substation indicates that Orhuwhorun feeder has a higher frequency of fault and from results obtained from Symmetrical method of fault analysis revealed that double Line to ground fault has the highest fault current and could cause adverse damages to equipments’and as such must be avoided. The fault current calculated from Symmetrical component method of Fault analysis was validated with computer program MATLAB as results agreed closely since error was below 0.1%.This paper analyzes several faults from an injection substation. The distribution network was modelled in ETAP, observing values for active and reactive power and voltage magnitudes
