What is the transformer oil recycling process?

The transformer oil recycling process involves several key steps. First, the used transformer oil is collected and filtered to remove particulate contaminants. Next, it undergoes vacuum distillation to separate water and lighter hydrocarbons. The oil is then treated with adsorbents or chemical agents to eliminate dissolved impurities and restore its dielectric properties. Finally, the recycled oil is tested for quality assurance before being reused in transformers, ensuring compliance with industry standards.
