Taking the wound core transformer widely used in the field of traction energy saving as the
research object and considering its unique geometric structure, combined with the magnetic …

This paper analyzes a practical methodology to assemble/combine commercial electrical
steels in a single‐phase core‐type power transformer. The main advantage of these …

This paper presents an electromagnetic finite element (FE) analysis of combinations of
electrical steels in the lamination core steps of a real 6.3 MVA single-phase distribution …

This paper presents a comparative evaluation of conventional and mixed magnetic wound
cores for three-phase distribution transformers. The authors utilize a techno-economic …

Introduction. With the adoption of standards to reduce losses in transformers it is necessary
to change the design of transformers that remain unchanged. Further energy saving is …

Three-dimensional wound cores are widely used in three-phase distribution transformer due
to the symmetrical magnetic circuit structure. Amorphous alloy and oriented silicon steel are …

Even though, the transformer is the most efficient of electrical machines, with efficiencies
typically in the high 90s, it is possible to reduce transformer costs and losses by using …

We report results continuing the research which looks at the influence of two different
magnetic materials in a core construction on the transformation errors of a current …

Medium power transformers are responsible of the great part of total power losses in the
grid. With EN50588-1 regulation, no-load and load losses have strictly classified fo r high …
