Power transformers are one of the most important components of the electrical power
networks. A wide range of mechanical and electrical stresses in addition to the aging could …

The condition of the internal cellulosic paper and oil insulation are of concern for the
performance of power transformers. Over the years, a number of methods have been …

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 a method of monitoring a power transformer's
mechanical integrity. However, identifying the type of fault and its severity by comparing …

The influence of nonuniform aging has not been considered in the prediction of the
frequency domain spectroscopy (FDS) of the transformer oil-paper insulation (OPI) when …

This paper presents an original data acquisition and transmission system designed and
optimized for on-line temperature monitoring systems in electric power transformers–system …

Frequency Response Analysis (FRA) technique is commonly used to assess the mechanical
integrity of power transformer core and windings. A few papers investigating the ability of …

Frequency response analysis (FRA) has been widely accepted as a diagnostic tool for
power transformer winding deformation faults. Typically, both amplitude-frequency and …

This study investigates the impact of electrical parameter variation of a high‐frequency
transformer model on its sweep frequency response analysis (SFRA) signature to help in …

Condition monitoring of large power transformers is of paramount importance in power
systems. One of the most common indicators of transformer aging is moisture content in oil …
