Between the end of 2008 and the beginning of 2009, Sea Marconi supplies a decontamination mobile system to Terna Partecipacoes S.A.(Brazilian branch of the Italian power transmission company Terna) to deal with the corrosive sulfur problem.
In following chronologically the situation, on 3rd November 2009 Terna Partecipacoes S.A. closet the sale of its 66% to Cemig (Companhia Energética de Minas Gerais), one of the largest operators o the electric power market in Brazil. This operation, as a fact, marked the exit of Terna from the Brazilian market and the transfer of the electric grid previously controlled by Terna Partecipacoes S.A. to Cemig.
The solution offered last year by Sea Marconi and the brilliant results achieved, positively surprised Cemig as well, confirming and validating the partnership with Sea Marconi. Our system sold in Brazil is currently engages in the selective depolarisation form DBDS of transformers and shunt reactors on the 500 kV transmission grid with the Chedcos technology, both in the on-load (energised and under load) and off-load (de-energised) modalities.
Thus the new operator Cemig validates the Sea Marconi technology, able to abate the DBDS, major cause for the corrosivity of oils, up to a concentration below 5 mg/kg, guaranteeing after 90 days, in any case, below 10 mg/kg.
