It is possible to determine the condition of a transformer by analyzing and diagnosing a sample of the insulating oil it contains. In the same way as for human beings, the oil that comes into contact with the internal parts of the transformer can provide important diagnostic information. Sea Marconi's DeosVision transformer fault prevention service involves a visual inspection of the oil, correct sampling techniques, suitable transport, laboratory analysis and subsequent diagnosis. The purpose of these activities is to detect even the slightest anomalies in the condition of the oil, and hence the transformer, and act accordingly, before they develop into catastrophic faults.

1. The first step of the prevention procedure is to collect samples based on the type of transformer and how it is used. Sampling may be performed by the customer or by our own staff.

2. Samples are sent to the Sea Marconi laboratory in Turin, where they are subjected to the acceptance and analysis phases.

3. The results are then examined by our experts, who draw up a complete diagnosis of the condition of the equipmentfrom which the samples were taken. This phase may involve a carrying out comparison with the vast quantity of information in the Sea Marconi database, the largest independent analytical database in the world (containing over 240,000 diagnoses). The diagnostic reports highlight any critical issues affecting the equipment and include information on the recommended measures that should be implemented in order to prevent unplanned and costly downtime.

If necessary, Sea Marconi can also intervene on-site, using dedicated units that perform a process similar to dialysis on the compromised fluids. This process removes any impurities from the oil and the machinery, thereby obviating the necessary for an oil change, with all the attendant costs and inconvenience. The Deosvisiondiagnostic fault prevention cover is just one of the many services that make Sea Marconi a leading company in the research, development and marketing of new solutions for the management of electric equipment with insulating fluids.
