Fuller's earth Transformer Oil Regeneration Plant
Transformer Oil Regeneration Machineï¼?transformer oil

Oil Regeneration Extends Transformer Unit Life

HOPU's mobile regeneration system restores transformer oil by removing acidity, sludge, soluble oil decay products and improves oil colour with Fuller's earth treatment technology. When the treatment is complete, the regenerated oil meets or exceeds international standards for new 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 effect of multiple passes of hot regenerated oil, which helps remove decay products and sludge from internal surfaces.

Advantages of Oil Regeneration

· Extends the transformer life by restoring the qualities of the transformer oil to be similar to new oil condition

· Oil Regeneration is much less costly than changing new oil

· Minimal downtime as a result no revenue loss as Oil Regeneration can be performed â??on-inline or liveâ??/ energized transformer

· Environmentally friendly as the existing oil is reused. There will also be no hazard from oil spills and PCB contamination, including the trouble with the disposal of old oil

· Oil Regeneration removes the sludge build up and deposited on the internal core and coils of the transformer, which a traditional oil change will not

· Oil Regeneration can be continuously performed in most weather conditions and will not run the risk of exposing the internal transformer core to adverse weather conditions during an oil change

This special vacuum oil water separator can shorten the oil treatment period for transformer installation and maintenance.

Why purify transformer oil? Maybe the first question should be, ¡°why is it important to have purified oil in a transformer?¡± Dissolved gasses in transformer oil can cause arcing, corona discharges, and overheating--reducing the electrical efficiency and lifetime of the transformer. Likewise, water contamination at levels as low as 30 ppm (parts per million) can adversely affect the insulating strength of the oil. With ever-increasing standards for energy efficiency of power distribution transformers, the need to effectively degas will become even more important in the future. particles contamination will also affect the function of insulating oil. So we need to clean used transformer oil.
