Transformer Oil Filtration

Transformer Oil Filtration is a vital process to remove moisture, dissolved gases, sludge, and other impurities from insulating oil. Clean oil improves dielectric strength, enhances insulation performance, and extends transformer life. Our services ensure your transformer operates efficiently and safely under all load conditions.

Applicable for Power, Distribution, and Special Purpose Transformers

Importance of Transformer Oil Filtration

Over time, transformer oil degrades due to oxidation, heat, and contamination. Regular filtration maintains oil quality, prevents internal arcing, and reduces the risk of unexpected breakdowns. It also delays the need for costly oil replacement or transformer overhauls.

Improves insulation properties
Enhances dielectric strength
Reduces moisture and sludge
Minimizes internal faults
Ensures long-term transformer reliability
Extends maintenance intervals

Scope of Filtration Services

We offer transformer oil filtration for voltage levels ranging from 11kV to 220kV. Our service includes oil testing, filtration under vacuum, degassing, and dehydration using multi-stage systems. Whether at substations, industries, or utilities, our trained technicians ensure optimal results with minimal downtime.

Detailed test reports including BDV, moisture content, and acidity are provided after service. Emergency and AMC-based filtration services are also available.
