Other services

Sea Marconi has a wide range of services that accompany those of the core business.
Some of these services are "accessories" dedicated to the world of transformers, others are for the world of lubricating oil or SF6 insulated equipment.

Sea Marconi's objective is always the same: to assist owners of machine pools - whether of transformers, turbines or SF6 circuit breakers - in order to ensure better life cycle management (LCM).
This means, for example, suggesting concrete actions and appropriate countermeasures to thwart impending critical problems and prevent catastrophic failures and unexpected downtime that immediately result in production losses and related penalties.

Revolving table

for the preparation of samples for DGA analysis

Revolving table

The Revolving Table is an instrument designed to streamline the preparation of insulating oil samples for dissolved gas analysis (DGA)by the gas chromatography technique in the head space and water-in-oilusing the Karl Fischer technique for extraction in nitrogen flow.Developed and validated by Sea Marconi in 1999, the revolving table is currently being used successfully in many laboratories internationally for routine work.

The instrument essentially consists of a rotating drum fitted with 28 placements for vials with 20ml head space, lined up with hermetic closures.

Sea Marconi's revolving table allows up to 28 vials (vials) to be conditioned under inert gas (argon)with a controlled flow, and the oil sample to be introduced without atmospheric contaminants (oxygen, nitrogen, CO2, moisture, dust, etc.)Sample dosing operations, positioning of the closure and closing of the vial (all under inert gas) are quick and easy with the convenient central hand wheel and the fact that the instrument is made of transparent plexiglass.

Our strengths

  • handling and dosing of samples in a controlled inert atmosphere (argon)
  • limitation of interference from atmospheric gases
  • preparation of 20 samples per man hour (approximately)
  • applicable to mineral insulating oils, synthetic insulating fluids, Askarels, silicone insulating liquids
  • can be used to prepare samples for storage pending analysis
  • highly repeatable system
  • minimal size
  • Conforms to IEC 60567:2011 "Oil-filled electrical equipment - Sampling of gases and analysis of free and dissolved gases - Guidance"
  • Significant improvement of performance in terms of quantification limits
