Abstract: Nigeria’s power supply has been experiencing incessant interruptions due to failures in the distribution system. The maintainability of the power system is important in meeting customers demand. The maintainability of three 11kv feeder in Benin Electricity Distribution Company (BEDC), Edo State Nigeria is evaluated in this study. The failure data which includes; time of failure, time outage was restored, causes of failure, and the failure time were collated and collected from the Injection substations of the three feeders for the year 2020 and 2021. Monthly and Yearly Mean time between failures (MTBF) and failure rate were calculated for the analysis. The analysis results revealed that the year 2021 had an increased failure rates than the year 2020 for the three feeders which implies a better performance.
Keywords: Failure Time, Repair Time, Maintainability, Mean Time to Repair (MTTR), and Repair Rate.
