The procedure for transformer oil regeneration includes several key steps:
Oil Heating: The oil is heated to reduce its viscosity.
Filtration: Solid particles, sludge, and other contaminants are removed using fine filters.
Vacuum Dehydration: Moisture and dissolved gases are removed using vacuum pressure.
Adsorption: The oil is passed through filters containing activated clay or other adsorbents to remove acids and oxidation products.
Dielectric Testing: The oil is tested to ensure it meets dielectric strength requirements.
Recirculation: The regenerated oil is reintroduced into the transformer to restore its insulation and cooling properties.
