The EuroDoble is one of the main appointments for the technical updating of the sector in Europe. This year the event was held in Rome from 25 to 28 October 2022 on two main topics: Asset Management and Digital Substations. At the invitation of Doble Sea Marconi had the honor of opening the technical part of the event (keynote speech)

We are very honored to have participated in the workshop “Treatment Technologies for Transformers’ Corrosive Sulphur” organized by our saudi partner GCC Lab in Damman (Saudi Arabia) the 26 and 27 Sept. 2022.  The event was attended by 50 engineers/technicians from different clients of GCC Lab and was focused on Asset Integrity Management. Sea Marconi attended the event with 4 very

After some difficulties imposed by COVID-19, last February 2021 the treatment campaign in Saudi Arabia kicked off. This is an activity out of the ordinary for the amount of electrical equipment to be treated, 23, their size, up to 130 tons of oil, maximum voltage and power (up to 380 kV and 500 MVA), and consequently the total amount ofRead more

Sea Marconi recently intervened to treat a transformer in a hydro-electric production plant in the north of Portugal, owned by EDP (Energias de Portugal), one of the largest producers of energy in Europe and one of the most important industrial groups in Portugal. The brilliant results of this activity earned Sea Marconi formal qualification by EDP (Labelec) for the “regeneration” of insulatingRead more

The 6th “Seminario de Tecnología y Diagnóstico de Transformadores y Fluidos Aislantes” in Monterrey in Mexico has just come to an end, involving the participation of speakers from Sea Marconi. The event was organised by Weidmann and Prolec (General Electric) for all operators involved in the selection, purchase and management of electric transformers with insulating fluid. Over the three days, many themes were dealtRead more

Sea Marconi recently performed an expert activity for the most important utility in Hong Kong. The service involved an analysis and diagnosis campaign on a large fleet of transformers and shunt reactors, for the purpose of verifying the presence of corrosive sulphur by DBDS (C1). The results of this activity allowed us to model the operating conditions of the Client’s machines and subsequentlyRead more

In accordance with the IEC 62701 standard (Fluids for electrotechnical applications – Recycledmineral insulating oils for transformers and switchgear), Sea Marconi has developed an ad hoc project for one of the most important European suppliers of transformer oils. The project involves the implementation of a system for the assessment (technical-economical and environmental) of insulating oil properties before and after their reclamation (oil regeneration). InRead more

L’eco The echo generated by the depolarisation from corrosive sulfur carried out last year on 5 transformers (170 tons of oil) at the Urrà power station is arousing considerable interest amongst owners of fleets of electric machines in Colombia. It is not by chance that major projects (e.g. Cali, Medellin, Bogotà) are taking life with the main public and private companies andRead more

Among the interesting outlooks at the end of 2013 there is the acquisition of an important order issued by the Brazilian TAESA, one of the largest groups for the transmission of electric power in Brazil. The subject of the sale is a containerised mobile unit (DMU) capable of performing an integrated treatment of the oil and transformers contaminated by corrosive sulfur, with a flowRead more

Among the “crown jewels” interventions of 2013, the selective depolarisation to remove the DBDS and polar compounds on 5 transformers must indeed be mentioned. In particular, the activity took place on 4 transformers and a rectifier (for a total of 170 tons of oil) operating at the Urrà, hydroelectric power station North-Western Colombia (read the article relative to the operation start). The said powerRead more
