Analysis of the Failures in Power Transformers

Abstract

In this study, the failures in Transformer Centers in Mersin Province Erdemli District have been investigated. The causes of the failures have been discussed. It is aimed to create a method for the reasons of possible failures of power transformer. The data have been collected by investigating the faults occurring at the Erdemli Substations. The failure statistics of the 200 power transformer failures that occurred between 2003 and 2019 in the Erdemli district of Mersin province have been examined. Examples of different power transformer failures have been given in fault analysis. The reasons of power transformer failures and the precautions to be taken have been explained.

Definition of Faults and Efficiency in Power Transformers Using the Algorithm and Computer Program Created by the Heuristic Optimization Methods Developed

“…Iron and copper losses must be equal to each other in order to ensure maximum efficiency. If the loss of copper, which is variable, is equal to the loss of constant iron at which load rate, the yield will be maximum at that load [41][42][43][44][45].…”

“…If it is not, iterations will continue from the beginning. In the algorithm, two parallel arms are combined below to find the best solution [41][42][43][44][45]. In this study, efficiency optimization in different loading conditions for power transformers was realized with the developed cuckoo and flower pollination hybrid algorithm.…”
