How does a transformer oil regeneration machine work?

A transformer oil regeneration machine functions by:

Heating and filtering the oil to remove solid impurities.
Vacuum dehydration to extract moisture and dissolved gases.
Adsorption with activated clay or other substances to remove acids, sludge, and oxidation by-products.
Recirculation of the regenerated oil back into the transformer to ensure its proper functioning. The machine operates as a closed-loop system, continuously purifying the oil until it reaches optimal conditions.
