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 SF6 in the oil is a symptom of an evolving criticality, especially relevant for step-up transformers used in nuclear and thermal power plants.
The wide applicative case history allowed Sea Marconi to validate the method and statistically classify typical values of alert and alarm; in this manner it is possible to support the operational decisions of the Users to prevent or mitigate damages also of a catastrophic type (explosion and fires). The new analytical method by Sea Marconi offers a specific response to those bearing the responsibility for the best management of fleets of equipment with insulating oils. Sea Marconi confirms being a leader, offering advanced, complete and reliable solutions in the activities for supporting the Life Cycle Management – LCM of transformers and related accessories.
