Transformer Oil Filtration and Regeneration

The electrical insulating fluids used in transformers undergo various degradation processes over time, leading to a loss of their original properties, which are essential for proper electrical insulation and cooling. We offer filtration and regeneration services that allow these fluids to be recycled rather than replaced.

Oil regeneration is a comprehensive process designed to restore all properties and parameters of transformer oil to the quality of new oil. Our services include both consulting and complete execution of transformer maintenance, oil filtration, and regeneration as a turnkey solution.

Comprehensive transformer maintenance includes:

Inspection of oil transformers, with or without removing active parts from the tank
Sealing transformers by installing a transformer conservator airbag
Cleaning and surface treatment of transformers
Comprehensive measurement of transformer insulation systems, including laboratory testing of oil
Inspection of distribution transformers in transformer vaults
Inspection and repair of control systems for power transformers
Filtration and regeneration of electrical insulating fluids, along with cleaning the active parts of the transformer
Scrapping of transformers of all capacities and voltage levels

Oil regeneration using our equipment and technology enables:

Removal of solid impurities, reduction of water content, increased dielectric strength, and degassing
Cleaning of the transformer’s active parts from residues of degraded oil
Reduction of tg ........................................ < 0.5% at 90 °C
Reduction of acid number ..................... to < 0.01 mg KOH/g
Increase of surface tension .................. to > 50 mN/m
Re-inhibition of oil ............................... to 0.30 ± 0.05%
