The aim of the article is to present the method of modeling the frequency response of the
transformer windings with axial displacements. Frequency response analysis (often referred …

Accurate modelling of power transformers is beneficial for fault diagnosis and the health
condition assessment of the power transformers. However, measuring the internal …

At present, the detection of transformer winding deformation faults is carried out in an offline
state, which requires the transformer to cooperate with the implementation of planned power …

At present, most of the winding fault detections of transformers use offline methods, which
require the entire line to be powered off or after the transformer has been shut down due to a …

Frequency response analysis (FRA) is a standard technique for monitoring the integrity of
the mechanical structure of power transformer windings. To date, however, there remains no …

In this work, fringing effect is studied on planar transformers for various frequencies, air gap
lengths, core materials and core geometries to aid engineers in choosing the best …

Power transformers are subjected to surge overvoltages which can lead to failure of the
windings insulation system. The amplitude of the overvoltages in the windings is dependent …

The mechanical and electrical stability of the power and distribution transformers is essential
by electricity providers and consumers. The transfer function method, specifically, Frequency …

Half-wave uncontrolled rectifiers play a pivotal role in converting sinusoidal alternating
current (AC) signals into direct current (DC) voltage. This study examines the impact of a …

Transformers are essential and costly components of an electric power system, and their
failure can lead to significant issues. Partial discharges (PD), which are localized electrical …
