Transformer oil regeneration machine insulation oil purification oil purifier
What to do if transformer has an excessive moisture content?
Water in transformers can be found in different parts of the insulation system.
It can accumulate in solid insulation, be dissolved in oil, or be found in the form of liquid water at the core or bottom of a transformer.
If it has been determined that a transformer has an excessive moisture content, either through water-in-oil analysis or dew-point analysis, the transformer should be dried out. Otherwise, the presence of moisture in the kraft paper will definitely shorten the life due to chemical decomposition through oxidation of the cellulose.
Drying out a transformer can be accomplished by untanking the core and coil assembly and drying it in an oven, but this would be both expensive and inconvenient. Fortunately, there are methods that can be applied in the field that are very effective in drying out a transformer.
Sino-NSH-VFD-R is a dehydration and degassing unit added with regeneration device. The regeneration device has built-in or individual as options.
Sino-NSH Regeneration device adopts a patented proprietary technology. It is widely used practical working fields which has successfully processed transformer oil, silicone oil, turbine oil, fuel oil, and industrial oils. It can restore the oil by removing colloid, pitches, sludge, or sulfur and hydrogen sulfide compounds as needed.
Sino-NSH-VFD-R maintains:
-Improves reliability of high voltage transformer
-Extends transformer service life
-Reduces oil purchase expenses
-Efficient adsorbent reactivation cycles
-Simplified operation
-Low maintenance
