Abstract
Distribution transformers are typically designed to operate under linear loading current. Nowadays, an emerging of modern electric loads that equipped with power conversion devices, it is inevitable that, the transformers are subjected to supply non-linear current. Those are resulting in a considerable increment of heat loss, temperature rising and shortening of insulation lifespan. In case of planning for retrofit or new utility system design, replacing conventional transformer with the low loss one is introduced. This paper therefore proposes a design and testing of low loss transformer using K-Factor and modified winding eddy current loss (WEC). Test results show that efficiency and temperature rise of the new design outperforms conventional one under standard testing of linear and non-linear loads.
