摘要

In this paper finite element method has been used which shows its effectiveness in designing a dry type transformer to determine the temperature rise. A 160 kVA VPI (Vacuum Pressure Impregnated) tap wound LT transformer having nominal voltage ratio of 415 / 415 Volt has been designed and subjected to a temperature rise test by simulation load method. A 3D finite element method using Variational Approach was adopted in designing the transformer to estimate the temperature rise under full load condition for linear loads.
