The aim of this paper is to present a new technique for estimating the contamination by
moisture in power transformer insulating oil based on the spectral kurtosis analysis of the …

The properly behavior of power transformers is highly dependent of the insulation health.
So, the insulation condition assessment can provide information to a system of diagnosis …

Transformer oil is an important liquid dielectric of oil-immersed transformers. Moisture and
temperature bring a great harm on the transformer insulation. This research was carried out …

Transformers are one of the most important equipment found in electrical power systems.
Thus, their status must be constantly monitored to avoid critical failures. The analysis of the …

In the paper is presented experimental analysis and diagnostics of insulating system oil-
paper for power transformers. In the first part of the paper is described base theory about …

Careful monitoring of high voltage equipments and diagnosing the critical conditions before
they lead to a disaster are prerequisites of condition‐based maintenance. Moisture content …

In this letter, partial discharge (PD) acoustic waves for different temperatures have been
detected using a piezoelectric acoustic sensor. The experiments results are analyzed using …

The ageing rate of cellulose insulation materials (paper/pressboard) in oil‐impregnated
transformers is largely determined by moisture. In this paper, several experiments were …

Partial Discharge (PD) is one of the symptoms of an electrical insulation problem, and its
permanence can lead to the complete deterioration of the electrical insulation in high …

Problem statement: Water detection in hydrocarbon emulsions represents a serious
challenge in petroleum production industry. The elemenation of measurment noises is also …
