However, this oil has started to be replaced by vegetable oils. Additionally, different authors have found that mineral oil-based nanofluids have a potential in improving insulating properties of transformer oil. In order to improve the characteristics of a commercial vegetal oil, this work has used TiO2 nanoparticles to obtain a nanofluid whose ageing behavior at 150°C for 300 hours has been studied.}, organization = {The authors of this research wish to thank the Ministry of Economy for financial support to the National Research Project: Improvement of Insulation Systems of Transformers through Dielectric Nanofluids (DPI2015-71219-C2 1-R).}, publisher = {Institute of Electrical and Electronics Engineers, Inc}, publisher = {35th IEEE Electrical Insulation Conference (EIC), Baltimore, USA, 2017, 1-4}, title = {Effect of TiO2 nanoparticles on the performance of a natural ester dielectric fluid}, author = {Fernández Diego, Cristina and Santisteban Díaz, Agustín and Ortiz Fernández, Félix and Delgado San Román, Fernando and Ortiz Fernández, Alfredo}, }
