Improvement of Transformer Core Loss by Use of Low-Loss Electrical Steel

  • Zvonimir Valković

Abstract

The results of an experimental investigation of the influence of high permeability grain-oriented (HGO) steel on transformer core loss are presented. The power losses of cores assembled with HGO material of grade M2H and with conventional grain-oriented material of grade M5 are compared. The aim of the investigation was to determine the influence of a number of parameters (e.g. single-phase and three-phase core forms, different corner and T-joint designs, core proportions, core dimensions, a number of laminations per stagger layer, overlap length) on the amount of loss reduction in the cores of HGO material.
