Summary: | This work examines the potential use of palm kernel oil methyl esters (PKOME) as liquid bio-insulators in distribution transformers. A mathematical model of heat transfer inside a transformer is developed and solved using COMSOL Multiphysics software. The results of the model are validated by experimental data, showing a temperature variation of 31–81.8 °C in the measurements and 31–82.5 °C in the simulation. This validation confirms the accuracy of the model in predicting the temperature distribution inside the PKOME-filled transformer, paving the way for their use in distribution transformers.
•We are studying the effect of using palm kernel oil methyl esters (PKOME) on the cooling of a distribution transformer.•We propose a mathematical model of heat transfer inside the transformer to determine the temperature distribution and the velocity field.•Our mathematical model is used to simulate the temperature evolution of our filled bio-insulator in a transformer selected from a real range of distribution transformers.•The results obtained are compared with the standard setting limit values for oil temperature in distribution transformers. |
