The course was designed for the training of technicians working in the electrical maintenance sector.
The agenda is designed for a duration of 1 day, including a half day of theoretical training and a half day of practical training through a site visit (or alternatively at the Sea Marconi office in Collegno (TO – Italy)) at the which transformer treatment activities are taking place. The visit to the operation site is an extraordinary educational opportunity, since live it is possible to touch the methods and process performances described verbally. At the same time the practical part allows to understand in depth the aspects, for example, of safety (for people, for assets and for the environment) that make Sea Marconi treatments unique.

    Properties of mineral oils and cause of degradation

    • Types and meaning of the tests, reference values.
    • Contents of the IEC 60296: 2012 ed.4 standard for new mineral oils
    • Contents of the Guide IEC 60422: 2013 ed.4 for the control of oils in service

    Equipment and treatment techniques applied to the decontamination of insulating mineral oils in power transformers

    • Explanation of the different processes in use by Sea Marconi and its practical applications:
      • Physical Decontamination Treatment (filtering, degassing and dehumidification)
      • Cellulose Dehydration Treatment (drying of active part in situ)
      • Selective Depolarization Treatment and Acidity (regenerated)
      • Dehalogenation treatment PCB (decontamination of chlorinated pollutants)
      • Selective depolarization treatment of corrosive sulfur (decontamination of sulfur compounds such as DBDS)
      • Treatment modalities On Load (in charge and voltage); Off-Load (without load and without voltage)
      • Specifications, process parameters and results obtained at the end of the treatment

    Theoretical session with supporting Power Point presentations.
