Abstract
Rapid advances and developments in the design, modernization, and optimization of transformers have generated an increase in power for the lines of distribution, with transformers occupying important positions in the national and international power systems.
This paper compares both the output parameters generated by the design process, the values obtained between 400 kVA transformers, a distribution transformer with conservative, and a hermetic transformer with air cushion (EPA). We use the same construction of the transformer core with columns and yokes made of a sheet of steel with angle-cut unoriented crystals and for the coils, use the copper conductor insulated with paper. The overall dimensions, the total mass of the transformers, the heating calculation, and their efficiency are compared.
It has proven that all materials used in the manufacture of a distribution transformer must have superior properties. Using the newest materials in the field we increase the performance of distribution transformers.
