Last August, a new and really useful norm has been published to better understand the “corrosive sulfur problem”; it is IEC 62697 ed.1 entitled “Test methods for quantitative determination of corrosive sulfur compounds in unused and used insulating liquids”. Particularly enlightening is the introduction of the standard (downloadable for the IEC website), in which, for the first time in the normative field, the DBDSRead more

A few days ago the fabrication of a plant for Mongolia, finalised toward the dehalogenation of electrical equipment with insulating liquids contaminated by PCBs was completed. This plant is of a DMU (Decontamination Mobile Unit) type with extremely innovative configuration and technical solutions. It is a plant made of two modules designed and developed in a manner allowing the operators to work insideRead more

Sea Marconi has recently started in Sweden a campaign for the decontamination treatment from PCBs with the ambitious target of 2 mg/Kg (ppm w/w). The activity, which shall have a total duration of about four months, involves the complete dehalogenation of 8 transformers with 15 tons of oil each at an important industrial site in Central Sweden. The Customer has chosen the “on-load” treatmentRead more

On 13th June the works for Rio+20, started, the United Nation’s conference organised in Brazil, exactly 20 years after the historical Summit of the Earth of 1992. Rio+20 will culminate with the presence of the heads of states that shall meet for the final session of the event from 20th through 22nd June. During the conference, seminars, workshops and other eventsRead more

On 10th May 2012, at the Belgian Embassy in Tokyo, Sea Marconi responded to the needs of Japan in identifying a solution to the PCBs problem in front of qualified participants coming from industry and the public sector, Sea Marconi teamed with two excellent European companies, the Belgian SITA Decontamination and the Dutch Orion. The three companies formed the consortium EES (European Environmental Solution) to provide theRead more

Sea Marconi has developed and validated an innovative method for the determination of both normal dissolved gases (DGA) and SF6 dissolved in mineral insulating oil. Thanks to a very advanced instrumental configuration it is possible to identify in a punctual manner particular troubles that could occur in bushings with oil and SF6 separated by a membrane. Thus, the contamination by SF6Read more

February 2012, new amendment to norm IEC 61181 “Mineral oil-filled electrical equipment – Application of dissolved gas analysis (DGA) to factory tests on electrical equipment”. This norm defines the criteria with which the analysis of gases is performed during factory tests, with particular attention for the heating tests. IEC 61181 goes into details over very specific topics, for example on sampling, the extractionRead more

Last February 2012 the 4th edition of norm IEC 60296 “Fluids for electrotechnical applications – Unused mineral insulating oils for transformers and switchgear” has been published. This norm, among other things, addresses the compilation of specifications and analytical methods referred to new mineral insulating oils. The oils in question are those used in transformers, switches and other similar electrical equipment in which the oil providesRead more

After one year from the trip by Mr Tumiatti to Mongolia, and almost two years from the visit by the Mongolian delegation to Sea Marconi, the path toward the acquisition of the know-how on the subject of management of PCBs continues a well as the attainment of the specific competences for the operation of an analysis laboratory. Sea Marconi stated the coachingRead more

The tests of the dehalogenation system (removal of PCBs from insulating oil of transformers) destined to Macedonia have been completed positively. Besides the supply of the system, the Sea Marconi’s solution includes a mix of high level products and services for the correct 360° management of the PCBs problem. From one side, the services for transferring the know-how, such educationRead more
