A silicone oil purification system operates by:

Heating the Oil: Reduces viscosity for better purification efficiency.
Vacuum Dehydration: Removes moisture and dissolved gases under vacuum conditions.
Filtration: Passes the oil through multi-stage filters to eliminate particulate contaminants.
Degassing: Extracts air and volatile gases that affect dielectric properties.
Adsorption Treatment: Uses adsorbent materials to remove acids and polar compounds.
Cooling: Returns the purified oil to appropriate temperatures before reintroducing it to the transformer.
This process restores the oil’s insulating and cooling properties, ensuring optimal transformer operation.
