Aging Transformer Oil Forms Sludge
As transformer oil ages, it oxidizes and begins to break down. The by-products of the degradation process include acids, aldehydes, and peroxides, which bind together to form sludge. Sludge attacks the cellulose insulation, inhibits oil flow, and traps heat inside the transformer. Eventually the dielectric gap is bridged, resulting in failure of the transformer.
Oil reclamation extends unit life
Utility Oils mobile reclamation system restores transformer oil by removing acidity, sludge and soluble oil decay products with Fullers Earth treatment technology. When the treatment is complete, the reclaimed oil meets or exceeds B.S.148, the standard for Reclaimed Insulating Oil, with lower acidity and improved tan delta, interfacial tension, and oxidation stability. The cellulose insulation and internal components of the transformer also benefit from the flushing affect of multiple passes of hot reclaimed oil, which helps remove decay products and sludge from surfaces.
Regular reclamation treatments every 8 to 12 years for each transformer in your network offers significant benefits.
- Reduced risk of unplanned outage and costly downtime
- Reduced maintenance costs
- Extended equipment life
Utility Oils Reactivation Technology
The best process for reclaiming transformer oil is treatment using Fullers Earth. However, conventional reclamation units are costly to operate, requiring large amounts of Fullers Earth which must be disposed of and replaced after each use. The oil Reclamation System features high-performance reactivation technology with Fullers Earth installed in the plant for two to three years The Fullers earth can be cleansed or reactivated 200 to 300 times before replacement is required. Oil can be processed continuously using the same charge of Fullers Earth. No disposal of oil soaked waste is required, greatly reducing the cost of operation.
