“…Feeders A1 to A5 are in group 1, Feeders A16, A37, A57, A70 and A71 are in group 2 while feeder A46 to A50 falls in group 3. The operational availability is probability that a system or equipment when used under stated conditions in an actual operational environment, shall operate satisfactorily at a given point in time [19,24]. This parameter is the one that the customers normally experience during their dealings with power utility company because it is used to measure the efficiency of the service provider.…”

“…The analytical techniques represent the system by a simplified mathematical model and evaluation of the reliability indices from this model using direct mathematical solutions; while simulation techniques, estimate the reliability indices by simulating the actual process and random behaviour of the system [5, 6, 16 -18] Furthermore, evaluation of reliability indices is classified into two main categories: repairable and non-repairable [19]. Repairable systems repair and put the system components back into operation after components failure, whereas a nonrepairable system fails to repair system components after components' failure, and thus a new one needs to be replaced [18,19 ]. However, most of the electric power systems' failures are repairable systems [19].…”

Distribution network planners carry out analyses of the power distribution network that may include studies like faults, sensitivity analysis and reliability assessment to enhance the robustness of the network. System reliability is the ability of the power system to provide an adequate supply of electrical power at a desired time without interruption. This paper focuses on reliability assessment of distribution network. It involves the determination of the reliability indices which explain the dependability of the system. Fifteen 11kV feeders are considered and the required data of the feeders to be used in this study were sourced from the chosen power utility company in Nigeria. A power system software called ETAP was used in computational process. The reliability indices of the chosen network were computed, and the results obtained are presented. From the results, the performance of these Fifteen 11kV feeders are classified into three; Best, averagely and poorly performing feeders, and they are highlighted using tables and charts. The results are discussed and analyzed. The findings from the study indicate that some feeders have very good reliability indices while some are having average values and others are with poor reliability indices. The most critical feeders that need improvement were identified.
