Investigation of the Economical and Technical Design Feasibility of Si-Fe Graded Distribution Transformers according to EN50588-1

Abstract: ÖzMedium 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-efficient transformer designs. Manufacturers are currently focusing on obtaining the most efficient design with minimum cost. In this paper, manufacturing feasibilities of Si-Fe graded distribution transformers, considering the requirements of EN50588-1 regulation, are investigated. Eleven different steel types in three grades a… Show more

“…As well as the technical features, economic feasibility of core construction should also be considered in transformer design stage. In [27], it is expressed that the feasible core designs for AA0 loss class could be obtained by using H grades. So, mixed grade cores, where H grades are used together with other grades, are evaluated for mixed core designs meeting AA0 loss class requirements.…”
