A fault analysis of 11kv distribution system (a case study of ado Ekiti electrical power distribution district)

Abstract

The aim of this research work is to carry out fault analysis of 11KV distribution power system. Electric power is an essential facilitator for sustainable development of the modern nation state. While Nigeria is reported to suffer from severe shortages of electric power the condition of some of its newer constitutional units are unknown. In this work, electric power infrastructure and energy availability is studied for Ado-Ekiti, the principal economic and political hub of Ekiti State. During the study, the condition of all relevant equipment for power distribution at the 11 kV level was assessed. Power availability was also considered by collecting necessary data that had to do with energy supplied, faults and other outages. It was discovered that the distribution lines were in a rather poor state with as many as 25% of the poles not meeting a condition of "goodness", 33% of cross-arms being broken or unsatisfactory, about 10% of the insulators defective and almost 40% of the span not complying with standards. Hence this work presents a research on fault analysis of Ado Ekiti distribution power system.
