Investigation of The Effect of Lamination Thickness on Temperature and Efficiency in Transformer
Keywords:Transformer, energy efficiency, thermal analysis, transformer losses
By 2050, all buildings in Europe are targeted to be zero-energy buildings. The use of fossil fuels in zero-energy buildings will be reduced as much as possible. Thus, the mainly used energy in the building sector will be electrical energy. It is appropriate to use dry-type transformers that do not have the risk of fire and explosion in zero-energy buildings. This eliminates the losses that will occur during transmission and enables a more efficient system to be used. In this study, transformer losses and their effects on efficiency and temperature change were investigated. For this, a 100 kVA dry-type transformer was simulated for two different material thicknesses used in the core, and core losses and temperatures were compared. As a result of the simulations, a difference of 20.5% in core loss and 6.8% in temperature was obtained between the two laminations.
