What is the transformer oil regeneration process?

The transformer oil regeneration process involves the removal of contaminants and degradation products from used transformer oil to restore its insulating properties. This typically includes filtration, adsorption, and vacuum treatment methods. During regeneration, activated clay or other adsorbents are used to absorb polar compounds and acids, while moisture is removed through vacuum distillation. The result is rejuvenated oil that meets the required specifications for effective insulation and cooling in power transformers.
