Abstract :

This study examines voltage variations in customer feeders and their impact on the performance of electrical transformers in the city of Boma, Democratic Republic of Congo. The research was motivated by a lack of in-depth analysis on the effects of voltage fluctuations on transformer reliability. To do this, an analysis of variance was performed using six transformers and voltage measurements taken on twenty-nine lines. The results showed a significant diversity of voltage levels, ranging from 127 to 195 volts, and confirmed that voltage variations affect transformer performance. It is recommended to install real-time monitoring systems and adapt transformer designs to local specificities. This study highlights the importance of rigorous voltage management to prevent outages and improve the reliability of the electrical network.
