Oil Reclamation

PSS Field Services also includes hot oil reclamation. The PSS hot oil reclamation rigs, which can be performed on energized transformers up to 230 KV, have purified millions of gallons of oil and prolonged the life of thousands of transformers. Because it's energized, the customer never has to take an outage.

Over time, byproducts are formed inside transformers that decompose the insulation system. These byproducts increase the water content and can cause the transformer to overheat and eventually fail. The PSS process extends the transformer life by removing the contaminants that attack the transformer's insulation system.

PSS circulates hot oil continuously through the rig in a closed loop path. The oil passes through multiple filters, fuller's earth, a vacuum dehydration column and a degassing column to remove contaminants, sludge, foreign particles, dissolved gasses and oil decaying byproducts contained in the oil. The heat from the energized transformer aids in dissolving sludge buildup and removing moisture from the insulation. Thus, the customer has a clean transformer with excellent oil properties.
