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 …

Power voltage transformers (PVTs) are becoming increasingly present in different substation
solutions on a world scale. Such units that are based on the open-core concept introduce …

Designing and manufacturing transformers often involves variations in heights and
thicknesses of windings. However, such geometric asymmetry introduces a significant …

This paper presents the results of new hexagonal configuration at the T-joint of three-phase
transformer core. The proposed model is compared with previous T-joint design, Butt-lap …

The use of new generation devices based on renewable energy is a subject that
increasingly becoming more important for the development of new distributed generation …

Power transformer differential relays may incorrectly operate due to inrush condition or
transformer external faults lead to current transformer (CT) saturation. In this paper, a new …

In this paper the lamination effect on the model of a power transformer's core with stacked EI
structure is analyzed. The distribution of the magnetic flux in the laminations depends on the …

Transformer life is primarily influenced by thermal, electrical, and mechanical stresses, and
each type of stress can be subdivided into time‐varying common stress from the normal …

Reducing the losses of 3‐phase transformers is still considered a significant target by many
transformer designers and manufacturers. Core joint design is one of the factors related to …

Purpose. The increase in energy costs and the need for further energy saving lead to an
increase in requirements for reducing losses in the magnetic cores of transformers and …
