The Electric Power Engineering Handbook, Third Edition updates coverage of recent
developments and rapid technological growth in crucial aspects of power systems, including …

A power transformer will yield a frequency response which is unique to its mechanical
geometry and electrical properties. Changes in the frequency response of a transformer can …

Synchronous machine is one of the critical power generation parts in the power system. Its
stable operation ensures people's normal economic activities. Winding is an essential …

The sudden outage of a transformer due to a fault can cause irreparable damage to the
electricity industry. Hence, by conducting momentarily inspections of the transformer's …

Power transformers are subject to winding and core deformations due to short circuit faults
and other environmental conditions. Majority of these faults are of progressive nature and …

In order to accurately model the transient behavior of transformer windings, we need models
with a large number of nodes and parameters. This paper proposes a model that has fewer …

This paper develops computational models for undeformed and deformed transformers,
using the finite-element method (FEM) to calculate frequency dependent parameters …

This paper discusses the application of Nyquist plot and two statistical indicators to analyze
the frequency response of power transformers. Five cases are presented based on both …

The paper discusses an improved modelling of transformer windings based on bacterial
swarming algorithm (BSA) and frequency response analysis (FRA). With the purpose to …

Abstract Impulse Frequency Response Analysis (IFRA) provides an alternative technique for
detection of mechanical type faults in power transformers among researchers. However, the …
