Micafluid’s Swiss technology used for the conditioning and purification of insulating oil has been widely used globally over the past century since 1913 and has offered excellent service and results for its respective customers. This vast experience over the past decades makes us the ideal partner for service and maintenance companies. Through research and development we ensure that our machines remain on the cutting edge and on par with the latest industrial standards and protocols.
As part of the transformer lifecycle management, regular servicing is essential. Micafluid is fully aware of the customer’s need to reduce the TOC (Total Owning Cost) thus our equipment has been designed to meet this challenge, thereby boosting performance.
All our oil treatment plants type VOP (variable oil purification), with variable flow control, are designed for the economical conditioning and drying of insulating oils using vacuum and micro pore filtration technology. This can be done safely over one pass or several passes for a variety of different insulation oils, depending on the customer’s requirements. Furthermore our units are PLC controlled, integrating fully automatic functions suitable for off-line (de-energized transformer) as well as on-line (energized transformer) filling, purification and filtration processes.
Expectations when treating insulating oil
• Low moisture content at plant outlet
• Low gas/air content at plant outlet
• Elimination of residual gas from the insulation
• Drying of transformer insulation
• Easy and safe operation
• On-line measuring and recording of process parameters
• Flexibility in application - various oil types and oil volumes
The only effective treatment for improving the dielectric properties of aged oils is the regeneration with Fuller’s Earth. The activated Fuller’s Earth, has the property to adsorb Carbonyl - and Hydroxyl - groups in oil, as well as small amounts of moisture.
The degree of moisture adsorption is insufficient to guarantee effective drying; however, treatment of the oil with Fuller’s Earth, combined with vacuum drying, yields excellent results. The unit consists of one or several adsorption columns, a filter housing and eventually an inhibition set.
Such a compact and mobile installation encompasses a combination of a two-stage oil conditioning set with an oil treatment plant type VOP and an oil regeneration unit type
CRP3000. Regeneration unit types CRP3000 are generally connected in series with a separate drying and degassing oil treatment plant type VOP.
Benefits and applications
• Reconditioning of aged insulating oil
• Removal of acidity
• Improvement of dissipation factor tan delta
• Improvement of oil colour
Having extensive knowledge in all aspects related to vacuum processes, electrical insulation and high voltage equipment, Micafluid AG is in pole position to assist users of oil reconditioning, regeneration units and processes.
