Una tesis doctoral viene firmada por una sola persona, pero hay mucha gente que de un modo u otro ha participado en que esta sea posible, por eso quiero agradecérselo a todas esas personas.En primer lugar, quiero expresar mi más sincera gratitud a mis tutores Dr. Juan Carlos Burgos y Dra. Belén García, por darme la oportunidad de realizar mi tesis doctoral con ellos. Su amplio conocimiento y su nivel de esfuerzo e implicación son inestimables para la finalización de este trabajo. Desde un primer momento creyeron en mi y me han ayudado en todo momento durante este recorrido de más de cuatro años. Gracias.También quiero aprovechar la oportunidad para agradecer a la Universidad Carlos III de Madrid la oportunidad que brinda ofreciendo los contratos predoctorales para poder cursar una tesis doctoral formándonos, además, como profesores. Así mismo, quiero agradecer al resto de personal del departamento de Ingeniería Eléctrica, especialmente al Dr. Guillermo Robles y al Dr. Juan Manuel Martínez con los que he compartido congresos y buenos momentos y a Cristina Vega por su buen humor todas las mañanas.Además, en el plano profesional tengo que dar mi gratitud a los profesores

“…e higher breakdown voltage of mineral oil-based nanofluids should be governed by the trapping mechanism created by the mixed nanomaterial related to the lower conductivity of the mineral oil nanofluids. In the case of natural ester nanofluid, the breakdown voltage of the natural ester nanofluid was also improved and reported in [41,42], even though the nanomaterials increased the conductivity of the natural ester nanofluids.…”

Mineral oil (MO) has been widely used in transformers because of its reasonable price and acceptable properties. Currently, alternative liquid insulations have been proposed with some excellent properties. Therefore, the mineral oil characteristics need to be enhanced for high performance to compete with such alternative liquid insulations. This paper aims to study the power frequency dielectric dissipation factor (tanδ) along with polarization and depolarization current (PDC) characteristics of the mineral oil-based nanofluid and natural ester (NE)-based nanofluid. Besides, Fourier-transform infrared spectroscopy (FT-IR) measurement of the test specimen was performed. Titanium dioxide (TiO2) and zinc oxide (ZnO) with 0.01% and also 0.03% volume concentration were used to mix with the unmodified liquid to create liquid insulation-based nanofluid. Then, unmodified mineral oil, unmodified natural ester, mineral oil-based nanofluid, and natural ester-based nanofluid were comparatively investigated. Tanδ at power frequency and the PDC characteristics of such liquids were examined. For PDC measurement, TiO2 clearly affected the polarization current and conduction loss factor, whereas ZnO evidently impacted the depolarization current and polarization loss factor. In the case of FT-IR test results, there was no significant change when the modified insulating liquid was compared with those of the unmodified insulating liquid.
