The present work aims at investigating the possibility of mixtures between naphthenic
transformer mineral oil (MO) and natural ester olive oil (VO). Ten mixture ratios between the …

In this study, results of polarisation and depolarisation currents measured on an insulating
liquid are presented. The goal is to contribute to a better understanding of mechanisms …

The aims of this work is linked to the problematic of electrical charges formation in power
transformer insulation systems. After being qualitatively evidenced, this paper focuses on …

In the mind of alternative to the conventional mineral oils used as insulating material in
power transformers, this work aims to study the electrical behavior of one of the …

This work aims to investigates the effect of the cathode interface on the aging process of
transformer oil. The mineral oil is stressed with two different metal electrodes and the …
