What are the steps involved in transformer oil reclamation process?

The transformer oil reclamation process involves several key steps:

1. Sampling: Collect oil samples for analysis to determine contamination levels.
2. Filtration: Remove particulate matter using mechanical filters.
3. Dehydration: Use vacuum or heat to eliminate moisture content.
4. Degasification: Remove dissolved gases through vacuum or thermal methods.
5. Chemical Treatment: Apply adsorbents or chemical agents to neutralize acids and remove polar contaminants.
6. Final Filtration: Conduct a final filtration to ensure oil purity before reusing or recycling.

These steps restore the oil’s dielectric properties and extend transformer life.
