The International Conference on Dielectrics Liquids (ICDL 2011), held in Trondheim (Norway) from 26th through 30 June, was the ideal place to present the results of a research carried out by Sea Marconi with the collaboration of the University of Turin and the Nikola Tesla Institute of Belgrade. During 18 months, the study benefited of the work done by several senior students who prepared their graduation thesis under the supervision of doct. Maria Rosa de Carlo of the University of Turin.
The synthesis of the research project was presented by Riccardo Maina (manager of the Sea Marconi laboratory) under the title “Copper Dissolution and Deposition Tendency of Insulating Mineral Oils Related to Dielectric Properties of Liquid and Solid Insulation”. The key topic is the tendency by mineral oils to form dissolved copper and to transfer it on the cellulose; study that also allowed to clarify some diagnostic mechanisms and criteria for oils contaminated by copper and the relevant effects on the dielectric properties.
The audience, 150 of the top world experts of dielectric liquids, followed the Sea Marconi presentation with great attention; Riccardo Maina was asked a lot of questions, many of them encouraging to continue the study, considered as interesting and important for the comprehension of the mechanisms of dielectric failure of the insulations.
We are thanking all the people that collaborated in producing the data used for this paper, in particular, Marco Facciotti, Virginia Trento e Michela Pittavino.
