What is a transformer oil regeneration and degassing system?

A transformer oil regeneration and degassing system is a comprehensive unit designed to restore degraded transformer oil by removing contaminants like water, dissolved gases, acids, and sludge. It includes:

Vacuum degassing chambers to remove dissolved gases and moisture.
Filtration units to remove solid particles.
Adsorption systems (usually activated clay or similar materials) to remove acids and oxidation by-products. This system is used to restore oil to its original quality, improving the performance and longevity of transformers.
