Transformer oil filtration is needed to maintain the insulation strength and cooling performance of transformer oil. Over time, transformer oil absorbs moisture, gases, sludge, carbon particles, and acids, which reduce transformer efficiency and can cause insulation failure or breakdown.
Main reasons for transformer oil filtration:
-
Remove Moisture
- Water reduces dielectric strength.
- Moisture can cause flashover and insulation damage.
-
Remove Dirt & Particles
- Dust, carbon, and metal particles create electrical stress points.
- Prevents arcing inside the transformer.
-
Degassing
- Dissolved gases form due to overheating or electrical faults.
- Filtration/vacuum dehydration removes harmful gases.
-
Improve Dielectric Strength (BDV)
- Clean oil withstands higher voltage without breakdown.
- Essential for safe transformer operation.
-
Prevent Sludge Formation
- Oxidized oil forms sludge that blocks cooling ducts.
- Filtration helps maintain proper heat dissipation.
-
Increase Transformer Life
- Reduces insulation aging.
- Prevents costly transformer failures and downtime.
- After Installation or Repair
- New or repaired transformers require oil processing before energization.
We at AKG performed transformer
oil filtration in a specialized and highly technical business that requires
expertise, advanced equipment, and strict safety standards. We at AKG use
filtration machines equipped with vacuum dehydration systems, centrifugal
separators, and fine particle filters to clean transformer oil. The process
generally involves heating the oil, removing moisture and gases under vacuum
pressure, and filtering out suspended particles. Modern filtration units can
restore dielectric strength, reduce acidity, and extend transformer life significantly.
