About Our Transformer Oil Filtration Service in Coimbatore

Transformer oil (insulating mineral oil) absorbs moisture and oxidises over time, reducing its dielectric strength and accelerating insulation breakdown. Ram Engineering's transformer oil filtration service uses high-vacuum dehydration to remove moisture and dissolved gases, restoring BDV to safe operating levels and extending transformer life.

Coimbatore is the "Manchester of South India" — a major hub for textile machinery, pumps, motors, and precision engineering, with a high concentration of SME manufacturers. With Ganapathy Industrial Estate, Singanallur, Peelamedu, Kurichi, and SIPCOT Perundurai driving demand for industrial services, our transformer oil filtration teams are deployed regularly across Coimbatore's key manufacturing zones.

  1. BDV (Breakdown Voltage) testing
  2. Dissolved Gas Analysis (DGA)
  3. High-vacuum dehydration and degassing
  4. Particulate removal to 1 micron absolute
  5. Post-service BDV and moisture content certification

Key Benefits

✔ Restore BDV above 60 kV (IS 335 requirement)
✔ Remove dissolved moisture below 10 ppm

Frequently Asked Questions

What is the minimum BDV for safe transformer operation?
IS 335 requires minimum 30 kV for transformers up to 132 kV. We restore BDV to 60–70 kV through filtration.
How does moisture get into transformer oil?
Through breathing (thermal cycling), breather failure, oil seal deterioration, and condensation inside the transformer tank.
Can transformer oil filtration be done live?
Filtration is performed with the transformer de-energised. Online filtering equipment is available for specific applications.
