The interest in developing new nanodielectric fluids suitable for electrotechnical applications has increased significantly in the last decade. Several authors have reported experiences on fluids manufactured using different base fluids and nanoparticles. Most of these studies are focused on the comparison of the thermal and dielectric properties of the nanofluids and the base liquids and most authors have found that the addition of nanoparticles to insulating liquids can lead to an improvement of their dielectric properties. This two-part paper analyzes the enhancement of the AC breakdown voltage of several nanodielectric fluids prepared by dispersing variable concentrations of Fe3O4 nanoparticles in a mineral oil. In the first part of the study, the performance of fluids that had been previously dried and degasified were tested. In the second part of the study the impact of the presence of moisture in the dielectric strength of the liquids is analyzed trying to get insight into the physical mechanisms that justify the observed enhancements when nanoparticles are added to insulating liquids.

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
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
