abstract: Power transformer is one of the most important
equipment in an electric power transmission and
distribution system. It is very essential in
ascertaining the reliability of any power utility. It
is therefore critical therefore that the power
transformer operates continuously in order to
offer reli11ble and efficient electricity supply.
Utilities arc therefore facing considerable
concern to ensure their critical asset's reliability
due to deregulation, increased demand, economic
pressures, and profit constrains. Most of the
power transformers develop faults and get
critical over a period of time.
This paper presents the major causes of power
transformers' failure and maintenance strategy
and optimization techniques presently being
adopted in Abuja Distribution zone. The results
of the study and analysis on 107 injection
substations serving about 3876 distribution
transformers show that the major contributing
factors includes: earth 1:1ults and over currents.
Useful recommendations based on new
technologies are presented on how to ensure that
power transformer would serve closer to its rated
output and life without sacrificing its integrity.
The paper will be of importance to power
systems managers and operators for improving
the reliability of transformers.
