“Our transformer oil filtration service removes moisture, gases, and contaminants from transformer oil using advanced vacuum dehydration and filtration technology. This improves insulation strength, enhances transformer performance, prevents breakdowns, and increases equipment life.”
Transformer oil filtration is a preventive maintenance service carried out to improve the quality and insulating properties of transformer oil. Over time, transformer oil absorbs moisture, sludge, carbon particles, and dissolved gases, which reduce transformer efficiency and increase the risk of insulation failure.
Our filtration service removes these contaminants and restores the oil’s dielectric strength, helping ensure safe and reliable transformer operation.
Scope of Service
The filtration process generally includes:
1. Oil Circulation
Transformer oil is circulated through a filtration machine.
2. Heating Process
The oil is heated under controlled temperature conditions to improve moisture removal.
3. Vacuum Dehydration
Moisture and dissolved gases are removed using vacuum technology.
4. Micron Filtration
Dust, sludge, and suspended particles are removed through fine filters.
5. Oil Testing
Oil quality tests are conducted before and after filtration, such as:
1.BDV (Breakdown Voltage) Test
2.Moisture Content Test
3.Test
4.Insulation Resistance Check
