Power transformers provide a vital link between the generation and distribution of produced
energy. Such static equipment is subjected to abuse during operation in generation and …

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 …

This paper reports the results of employing an artificial bee colony search algorithm for
synthesizing a mutually coupled lumped-parameter ladder-network representation of a …

It is inevitable for power transformers to suffer from multiple impacts of short-circuit (SC)
current and huge dynamic electromagnetic force in service, which may cause large elastic …

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 …

ABSTRACT A transformer is a vital component in any power system network and its
catastrophic failure may cause disturbance in the proper operation of electrical power …

Fault localization and severity evaluation of transformer winding is crucial for its mechanical
condition assessment. Ladder network synthesis of winding entity based on its frequency …

Frequency Response Analysis (FRA) has been utilized as an off-line diagnosis test since
last decade to investigate mechanical integrity of transformer. FRA data typically reports as a …

This paper employs a hybrid model of a disc-type transformer winding for frequency
response analysis (FRA) of winding deformation and measurement parameter influence …

A novel procedure to determine the series capacitance of a transformer winding, based on
frequency-response measurements, is reported. It is based on converting the measured …
