• We know everything about transformer oil
• 20 years of experience
• > 5 mil. tons of oil regenerated
• > 250 transformers
• > 30 transformers with corrosive sulfur
• Clients using our equipment ABB, Siemens

3. REOIL Technology
Copyright 2017 | STACO
• Corrosive Sulfur removal
• Complete Oil regeneration like new oil
• Highly effective moisture removal
• Decrease in total sulfur content
• Highly efficient elimination of DBDS
• Mobile unit, Works on site
• Works on a live transformer

4. Filtration vs Regeneration
Copyright 2017 | STACO
• Filtration removes primary contamination of transformer oil –
i.e. moisture and gases.
• Regeneration removes completely corrosive sulfur and aging
byproducts – (micro particles of paper , wood and copper
reaction)
• Improves :-
– Tan delta
– Viscosity
– Acidity – ( Neutralization)
• Regeneration also improves the color of the contaminated Oil

5. Risk Factor
Copyright 2017 | STACO
• Corrosive oil
• High working temperatures
• Insufficient maintenance
• Overloading of transformer
• Insufficient cooling

6. Which transformers are at risk?
Copyright 2017 | STACO
• Primarily transformers built between 1999 – 2007
• Transformers after maintenance
• Transformers after oil exchange
• Transformers after top up of oil
• Transformer already passivated

7. REOIL Plant
Copyright 2017 | STACO
• Ability to economically regenerate used transformer oil
• Removes acidity , sludge and other ageing byproducts
• Ability to regenerate adsorption media such as fuller earth
• Entire process consists of two phases
Regeneration phase
Oil is heated then pumped through
columns where activated media
attracts ageing by products. Oil is
then filtered and directed into the
vacuum chamber for degassing
Reabsorption phase
Starts when activated media is fully
saturated by controlling temperature,
time, vacuum etc. Activated media is
restored into original state. Process can be
repeated more than 400 times before
replacement

8. Performance
Copyright 2017 | STACO
• Single column can process +-550 liters of aged oil
• Real life results exceed IEC 60422 values
Property (Unit) IEC 60422 Value REOIL Guaranteed Value
Dielectric Strength (kV/2.5mm) ≥50 ≥75
Dielectric Dissipation factor at 90℃ <0.01 <0.005
Neutralization number (mg KOH/g) <0.03 <0.01
Water Content (ppm) <10 <10
Interfacial Tension (mN/m) >35 >45
