How we work
Protection of the strategic machinery fleet
TransfoClean is based on the analogy between men-blood and transformer-oil.Similar to the way clinical diagnostics are performed, Sea Marconi monitors the state of health of transformers by analysing (and diagnosing) the oil inside them.

DGA EXPERIENCE – Improve the performance of your lab
DGA Experience is a package of products, instrumentation, assistance, advanced training and specialist consultancy, designed for new laboratories or for those who intend to improve their performance by respecting the requirements of the standards
Revolving table, samples preparation for DGA
The Revolving Table is a tool designed to improve the preparation steps for insulating oil samples destined for Dissolved Gas Analysis (DGA) with the gas chromatography technique in the head space. Developed and validated by Sea Marconi in 1999, the revolving table is currently being used successfully in many laboratories internationally for everyday work.
Kit for on site PCB screening in oil
The insulating liquids and related systems are classified respectively as “PCB” and “systems containing PCBs”, when the total concentration of the PCBs (209 possible congeners), PCTs (polychlorinated triphenyls – 8557 possible congeners) and PCBTs (polychlorinated Benzyltoluene) exceeds the limits stated by national laws.
SmartNosy RT – Health state monitoring of cast-Resin Transformers
SmartNosy RT (Resin Transformer) is the last innovation of Sea Marconi; SmartNosy RT is a Diagnostic and Prognostic service for monitoring the heath state of Resin Electrical Transformers.
Kit to measure total corrosive sulphur on site
The SM-TCS Kit (Sea Marconi – Total Corrosive Sulphur) continues to be the only truly effective and reliable solution to know precisely how corrosive an insulating liquid is.
The need to develop a quantitative method arises from the fact that in many cases, by running the CCD Test (IEC 62535) of oxidized oils, the visual outcome easily leads to false positives creating undue alarm.
Oil Sampling Kit for Hermetic Equipment
This kit can be used for oil sampling from hermetic transformers and electrical equipment.
The hydraulic couplings provided with this kit are also suitable for sampling of oil or free-gases from Buchholz relay.
StabOx, high-precision lab equipment to support oxidation stability test
StabOx performs the accelerated aging of liquids under controlled conditions with great precision, the equipment fully complies with all the requirements of the reference standard (IEC 61125* ed. 2.0 2018-01) but starting from those it is able to offer much higher quality standards.
TransfoClean is the brand that contains the line of core business products and services; these are solutions to support the management of the Life Cycle of electrical equipment with insulating fluids
My Transfo is the most important European conference on the management of transformer fleets and insulating oils. Since 2002 it is the most awaited event for professional updating and the exchange of experiences among professionals
