On 11th November 2008, Sea Marconi participated at the GCC Power 2008 in Baharain, the fourth GCC Cigre International Conference. Vander Tumiatti, founder partner of Sea Marconi, participated as speaker to the session titled Power Transformers and Substations.The presentation fully responded to the expectations generated by the topics in the title itself “Green Program D5 for the protection of fleets of TransformersRead more

I was made aware, in the most complete astonishment, of the departure of Viktor Sokolov, and I wish to express my deepest sorrow. I learnt with the greatest suffering and affliction about his departure from a letter sent by his children (here below). Through the years when our roads have crossed each other’s, I realised how he represented a lighthouse for theRead more

With pride we publish an abstract from OFFICIAL GAZETTE of the Republic of Italy of 7 June 2007 by Ministry of the Environment and the Protection of the Territory and the Seas.This legislative document implements in Italy European Directive 96/61/EC known as “IPPC” for the enacting of the guidelines for the identification of the Bets Available Techniques allowing the competent national and regional authoritiesRead more

An Italian company, Sea Marconi, together with University of Turin have synthesized and patented a type of macromolecules, nanosponges, starting from natural oligosaccharides, cyclodextrins. These compounds can be exploited in several applications thanks to their unique and peculiar structure enabling the inclusion of several substances, that can be either strongly retained or released in a controlled way. So far, theRead more

It is very important to take samples of paper from the windings of transformers at the end of their life, to improve the models of furans interpretation and to have indications on the thermal aging of similar equipment. A brief list of controls on failed/dead transformers is: Visual inspection of windings degradation Paper DP, sampling from higher side of windingsRead more

The estimation of residual life of the transformer (even in approximation) is a dream. However is possible, by adequately monitoring some parameters, to estimate the state and rate of thermal degradation of papers. This can be made with different approaches. Equivalen DP estimation: Some authors defind relationships between 2-FAL concentration (or better total 2-FAL generated) and DP of the paperRead more

A group of 4 industrial transformers (25 MVA, 15/6 kV), in a petroleum refinery. Installed on 1993, one of them has an electric failure on 2004. The fault is later identified as due to corrosive sulfur (detachment of copper sulfide particles from naked copper, LV side, discharge to earth). Meanwhile the manufacturer repairs the equipment, and refill it with theRead more
