From 23 to 27 June 2019 in Rome, Sea Marconi will participate as speaker and silver sponsor at the ICDL – IEEE International Conference on Dielectric Liquids. The ICDL, at its twentieth edition, hosts the major experts in the sector and is undoubtedly the event of the year for all professionals engaged in various ways in the management of the life cycle (LCM) of electrical equipment and insulating fluids.

The intervention of Sea Marconi will be entitled “Corrosions & PCBs: Inventory, Diagnostics and Treatments of Oils and Transformers”, (see. abstract below)* and offers a Risk Management and Asset Management approach on equipment with insulating fluids such as transformers . In particular, the paper technically describes the solution to two important critical issues (“pathologies”): corrosion and PCBs contamination. Sea Marconi is able to provide a complete response by offering a service of absolute excellence in fluid analysis (thanks to Accredia accredited laboratory), in the diagnosis and prognosis of critical issues and in the treatment of oils and transformers.

At the ICDL Sea Marconi will also present a poster (click here to open) entitled: “Life Cycle Management of Natural Esters & Transformers according to IEC Standards: Case History of Envirotemp^TM FR3^TM Fluid & TransfoClean^® Bio Solutions in Brasil.” This study, conducted in collaboration with Cargill, the Sapienza University of Rome and the University of Missouri (Rolla – USA) expresses the commitment and direction of Sea Marconi in being a pioneer also in the field of natural esters, a product that reflects the natural propensity of the company to look for environmentally sustainable solutions.

Conference Agenda

*Abstract
This paper describes the “State of the Art” for inventory, diagnostic, prognostic and integrated treatment of electrical equipment and insulating liquids containing DBDS/Corrosions & PCBs (Tech Pathologies). The Corrosions determine functional risks for transformers and equipment filled with mineral insulating oils: C1-DBDS &Corrosive Sulfur; C2-NOT DBDS &Corrosive Sulfur; C3-.SCBP & Corrosive Sulfur; C4-NOT Corrosive Sulfur &Metal Dissolution.
The PolyChlorinatedBiphenyls (PCBs) are a “Persistent Organic Pollutants” (POPS), as “Class 1.Cancerogenic to humans (IARC 2013) and determine risks for workers, public health and environment.
The oils & transformers integrated treatments, PCBs dehalogenation technique (“DMU & CDP Process” patented by Sea Marconi) and DBDS Selective Depolarization, in continuous mode through a closed circuit process are the sustainable solutions (Therapies) based on “circular economy”.
These solutions are based on the use of Smart Decontamination Modular Units (DMUs) and a solid reagent, consisting of a higher molecular weight glycol compounds, a mixture of bases and radical promoter or other catalyst on a high surface area particulate support. These processes normally run at 80-100 °C and have the capability to decontaminate equipment on-site through continuous circulation of the oil in a closed system (without draining the oil or using auxiliary tanks), using the solvent capability of the oil for continuous extraction of PCBs and DBDS from solid materials inside the equipment (according IEC 60422 art. 11.4.4).
International experience of diagnostic, prognostic and integrated treatments according to IEC & CENELEC include On-Load treatments in power transformers and shunt reactors, in several countries are presented.

Keywords — Transformer, Oil, Additives, PCBs, DBDS, Corrosive Sulfur, Total Corrosive Sulfur, Integrated Treatments, Selective Depolarization CDP Process, Dehalogenation.

As already anticipated by an article of June 2010 published on this web site, Sea Marconi, in collaboration with the University of Turin¹ (Dept. of Analytical Chemistry), University of Missouri (“Rolla”)² and the Serbian research Institute “NIKOLA TESLA”³, is engaged in a research project promoted by the Ministry of Economic Development favouring the integration between Universities and enterprises at international level.

The studies, started on 16^th November 2009 are in the final stages; the end of the activities is scheduled on 16^th May 2011.

The “Project n° 31. Life Cycle Assessment study of metal contaminated large power electrical apparata” has the objective of deepening the phenomenon of the formation and presence of metal contaminants in insulating liquids used in high power electrical equipment (transformers, reactors, rectifiers) used in the generation, transmission, distribution and application networks of electric power. This topic, already subject of investigations by normative groups in this sector (IEC, Cigre, ASTM, Doble, etc.), can cause the degradation of oils and equipment also with catastrophic consequences. The financial impact on international scale of such failures and the resulting blackouts, is in the range of billions of Euros.

After more than five years since the discovery by Sea Marconi and Terna of DBDS (DiBenzylDiSulphide), a sulphurised compound responsible for failures due to corrosive sulphur, it surfaced that corrosive oils exist also when such substance is not present. This involves the importance of the research of other potentially corrosive sulphurised substances in the oil and the evaluation of their effects in presence of copper and insulating paper.

For what the first results of the research are concerned, it has been pointed out, first of all, the considerable corrosive action of sulphurised compounds such as sulfoxides, which role in the formation of copper sulphide (CuS) till now has been considered secondary. It has also been observed, that as well oils considered not corrosive show the capacity of transferring important amounts of copper on the cellulose. Finally, through the examination of real samples, it was possible to deduct that the dielectric losses of the oils are mainly influenced by the fraction of soluble copper rather than by the particle one.

This project has seen Sea Marconi on the front line with the objective of deepening, in a pioneering way, dynamics still not clear on the international scenario with the purpose of identifying solutions to extend the life cycle of electrical equipment, while respecting and protecting the environment.
