The transformer is critical equipment in electrical power systems as it is continuously
exposed to various failures. Inter-turns fault in the transformer reduces the turns of the …

Frequency Response Analysis (FRA) is the most reliable technique currently used to
evaluate the mechanical integrity of power transformers. While the measurement devices …

Frequency response analysis (FRA) is a method of monitoring a power transformer's
mechanical integrity. However, identifying the type of fault and its severity by comparing …

This paper presents a new investigation to detect various faults within the three-phase star
and delta induction motors (IMs) using a frequency response analysis (FRA). In this regard …

Electrical power transformers are the most exorbitant and tactically prominent components of
the South African electrical power grid. In contrast, they are burdened by internal winding …

Power transformers are located in the electrical transmission and distribution networks
where different voltage levels are needed. The turn ratio of the low voltage and high voltage …

The industry has widely accepted Frequency Response Analysis (FRA) as a reliable method
to detect power transformers mechanical deformations. While the FRA technique has been …

This paper proposes a rational approximation-based approach to find positive real
parameters for the extended Debye model (EDM), aimed at condition assessment of …

This paper describes precise tests of frequency–temperature relations of the phase shift
angle and admittance of a reference sample of composite of cellulose and insulating oil with …
