High temperatures may damage power transformers. These problems leading to the high
temperature are more revealed under non‐rating operating conditions such as unbalanced …

The magnetic flux distribution in the transformer core, and particularly at the joints, has a
considerable influence on the efficiency of the core. This paper considers a more realistic …

This paper proposes a model for the computation of core losses and excitation current, in a
lamination by lamination method, for wound core distribution transformers. The model was …

Magnetostriction is an important source of vibration and acoustic noise in electromagnetic
cores. This study reports magnetostriction components along the rolling, transverse and …

Inrush current has been well-studied in transformers using different methods to diagnose
internal faults. In this paper, a new methodology is proposed using experimental data for …

By 2050, all buildings in Europe are targeted to be zero-energy buildings. The use of fossil
fuels in zero-energy buildings will be reduced as much as possible. Thus, the mainly used …

Evaluations of local induction time patterns () in transformer cores show high relevance for
both losses and magnetostriction. This paper presents numerical calculations for a three …

Grain-oriented (GO) electrical steel (ES) laminates are still very important in industrial
applications due to their remarkable crystallographic properties. Cores of large electrical …

A subproblem finite element method is developed for modeling the transformer core joints. It
applies magnetostatic and magnetodynamic models on progressive geometries and …

The contributions of this article are the analysis and economic evaluation of the impact on
tank wall losses of a diameter reduction of low-voltage bushings of pole-mounted single …
