A power distribution transformer is also popularly known as an isolation transformer. It changes high voltage to low voltage applied in electric energy distribution. Thus, it provides the final voltage transformation in the electric power distribution system. In general, the level of a distribution transformer is less than 200 MVA. Needless to say, some national standards allow for ratings up to 5000 MVA to be in the category of distribution transformers.

Maintenance for power transformer failures encompasses three main aspects, as detailed below:
1.Preventing Lightning Strikes: During adverse weather conditions such as strong winds, heavy rain, or thunderstorms, a power transformer's resistance to lightning can become compromised, making it vulnerable to failure due to damage to its insulation properties. Therefore, maintenance for power transformers should place a high emphasis on preventing failures caused by lightning strikes. First and foremost, effective lightning protection and lightning rod systems should be installed at elevated positions around the power transformer.
2.Ensuring Proper and Safe Grounding: It is essential to ensure the correct and safe grounding of power transformers. It is advisable to conduct on-site surveys of the specific installation location and positioning to avoid the presence of tall trees, buildings, or other structures in the vicinity. Furthermore, preventing electromagnetic interference from affecting the power transformer is crucial. In general, sound insulation protection can effectively prevent electromagnetic interference.
3.Addressing Short Circuits in the Electrical Network: Line short circuits are a common occurrence in power supply. Maintenance focuses on:
(1) Paying attention to the condition of the power transformer windings. During the design of power transformers, the relationship between winding processes and line short circuits should be fully considered.
(2) Ensuring that all materials used are of high quality and possess excellent performance.
(3) Installing relay protection devices within the power transformer. These devices can effectively interrupt the source of damage before it occurs.
