Abstract:
Electricity is produced and delivered to customers through generation, transmission and
distribution systems. A stable and reliable electric power supply system serve customer loads
without interruptions. Distribution systems deliver power from bulk power systems to customers.
Distribution reliability primarily relates to equipment outages and customer interruptions. This
study presents the assessment result of the power distribution reliability for Arba Minch
Distribution system of Secha Feeder (Feeder-03) and the possibility of using smart reclosers for
improving the urgent and pressing power interruption problem. The smart reclosers are key
elements for fault detection, isolation and restoration. The Electrical Transient Analysis Program
(ETAP) software has been used to verify the improvement of the reliability indices for the
distribution system.
