What is the process for the reclamation of used transformer oil?

The process for the reclamation of used transformer oil involves several steps. Initially, the used transformer oil is collected and filtered to remove particulate matter. Next, it undergoes vacuum distillation to separate water and lighter hydrocarbons. Chemical treatment may follow to neutralize acids and remove polar compounds. Finally, the reclaimed transformer oil is tested for quality and can be reconditioned for reuse in power transformers, ensuring it meets industry standards.
