In this study, 3D Conjugate Heat Transfer simulations are performed to determine the flow
and temperature distributions in a disc-type transformer winding. The results show that …

Power transformers are the first devices used to transfer the electrical energy produced in
power plants to the grid to supply the industrial and individual receivers with electricity. The …

In this paper, a numerical scheme has been developed to examine the effective parameters
on thermal management of distribution transformers and subsequently to optimize their …

Vegetable oils due to their unique properties of availability and biodegradability can be
considered as a reliable substitute for petroleum-based oils in transformer cooling system …

Kraft paper in combination with dielectric oil is the most common as insulation system used
in power transformers. The most used oil in power transformers is mineral oil. However …

This contribution presents the early results of a R&D collaboration established between the
University of Cantabria and the Power Transformer Manufacturer EFACEC. This paper tests …

This study was focused on predicting the temperature of power transformers, which is a
critical factor affecting their reliability and efficiency. Existing methods typically use a static …

In this paper, numerical investigation of oil flow distribution and temperature distribution is
performed for a disc-type transformer winding in an oil natural (ON) cooling mode. First …

Oil-immersed transformers are the core equipment of power systems for energy transfer. The
thermal characteristic of a transformer immediately affects its operational reliability and …

In this paper, measurements are carried out on four different washer arrangements of an ON
disc-type power transformer winding scale model. The experimental setup comprises a …
