The Oil Treatment Processes

Mainly there are three types of oil treatment processes:
Filtering
Purification with Drying Process
Regeneration of Reclamation with Degassing
The Filtering Process involves transformer oil filtration at a temperature of about 40 degrees Celsius. The process filters fine contaminated particles with the help of a filtering device.

The Purification with Drying Process heats the oil to a maximum temperature of 90 degrees Celsius and removes acidic & polar components from the transformer oil. A process of degassing under vacuum follows.

The Regeneration of Reclamation with Degassing is similar to the Purification with Drying Process but uses extra oxidant additives. This is the most effective method by which the oil can be regenerated in a cost-effective manner. However, the safety of the environment must be considered before undertaking this process.
