Electronic waste can lead to the accumulation of environmentally and biologically toxic
materials and is a growing global concern. Developments in transient electronics—in which …

Transformer liquid dielectrics evolved where mineral oil has been the dominant choice until
emergence of synthetic esters and natural esters. Natural ester-based oils have been under …

The dielectric performance of mineral oil and natural esters is still a challenge that has been
studied for many years to attain the best liquid insulation for power transformer. With the …

Moisture is one of the most harmful agents for transformer solid insulation. The catalyzing
effect of moisture on the degradation process of paper and pressboard has been studied by …

This article presents a comparative study of two types of transformer solid insulation:
standard Kraft and thermally upgraded Kraft papers. The paper samples were impregnated …

This paper deals with the experimental study of the behaviour of creeping discharges on
pressboard immersed in aged insulating liquids, in this case palm kernel oil methyl esters …

Power transformers use Kraft paper, thermally upgraded Kraft and other polymeric papers
(ex. Nomex) as the main solid insulation between the winding conductors. Dielectric oil used …

This paper presents a new method for analysing creeping discharges based on information
theory as it applies to medical imaging. The analysis of information surface data is used to …

Palm kernel and castor oils are two vegetable oils available in tropical climates which have
been proposed as an alternative to mineral oils, and their methyl esters, also called …

Vegetal oils are considered a suitable substitute for mineral oil that is widely used in power
transformers as insulation and cooling medium. Due to the fact that more and more power …
