Abstract

------------------------------------------------------ABSTRACT---------------------------------------------------The purpose of distribution system is to take electric power from transmission system and deliver it to customers to serve their needs. However, a significant portion of the electric power that a utility generates is lost in the distribution process. Power losses in Ekpoma distribution network were computed from data obtained from Power Holding Company of Nigeria, Ekpoma for five years (January, 2008 to December, 2012). The results were shown graphically. The results reveal that distribution losses in Ekpoma are due to technical and nontechnical losses. The technical losses are due to resistance and reactance of the conductors and faults. Several factors which includes unbalanced loading of transformers, transformer leakage current, aged transformer, damage accessories, inadequate size of conductors were discovered to have also attributed to power losses in Ekpoma. Suggestions were made in order to reduce power losses in Ekpoma distribution network.
