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.
