Causes of failure of Distribution transformer and its remedial measures

Hitendrasinh C. Chawda

Abstract :

  A Distribution Transformer (DT) is utilized to step down the voltage from 11 KV to 0.433 KV/0.250KV so that the electrical power is usable for providing supply to the customers such as domestic, commercial, industrial, LT, etc. A registered consumer expects uninterrupted power supply because during the failure of power supply, all works be it domestic, official, commercial or industrial comes to a standstill. Hence, transformer failure leads to consumer complaints and unnecessary emergency for the Utility to restore the power supply. In urban areas, the reason for failure of power supply due to failure of transformer is not too frequent, whereas in rural areas most of the power failures are attributable to the failure of distribution transformers. Failure of distribution transformers results in considerable revenue loss and entails heavy expenditure for replacement. This paper is on DT maintenance and reduction of failure, it does not describe the engineering know–how of prevention but ensures the use of these skills from the huge collective knowledge of our vast human resources.
