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.
