What is a used transformer oil processing rig?

A used transformer oil processing rig is a specialized system designed to purify and rejuvenate used transformer oil. This rig typically employs techniques such as filtration, dehydration, and degasification to remove contaminants, moisture, and gases from the oil. By restoring the quality of used transformer oil, the processing rig helps extend the life of power transformers and ensures they operate efficiently, maintaining electrical insulation properties and reducing the risk of failures.
