The increasing application of non‐linear loads in power system causes additional losses in
transformers resulting in premature damage. Manufactures and users of transformers realise …

The high-voltage (HV) assets in the existing power transmission network will experience
increased electrical, thermal, environmental and mechanical stresses and, therefore, robust …

In order to elucidate mechanical impacts affecting the insulation strength of thermal‐ageing
oil‐impregnated pressboards, we perform mechanical degradation experiments of impacting …

For continuous or spiral windings which feature multiple continuously transposed
conductors (CTC) wound in parallel, the transposition structure is commonly used to …

A transformer is the most valuable and expensive property for power utility, thus ensuring its
reliable operation is a major task for both operators and researchers. Online impulse …

Deformation of the windings is one of the main causes of the power transformers failure.
Here, for the first time, the electromagnetic forces exerted on the windings are computed in …

Supplying non‐linear loads causes increased losses in transformers which eventually leads
to their reduced life spans. Therefore, transformers are derated in order to protect them …

Owing to increasing power demand, new technologies, such as solid-state transformers, are
progressively researched and improved. Thereby, galvanic isolation and voltage adaptation …

In transient conditions, electromagnetic forces are produced. Due to these forces, radial and
axial displacements in the winding and insulation damage occur. In this paper, short-circuit …

This paper proposes an algorithm for the calculation of short circuit forces on the high
current busbars of electric arc furnace (EAF) transformers based on the method of images …
