What is the process of transformers oil filter machine and when is it required?

The process of a transformer oil filter machine involves the removal of impurities, moisture, and gases from transformer oil to restore its insulating properties. This typically includes stages such as pre-filtration, vacuum dehydration, and fine filtration. It is required when transformer oil shows signs of degradation, such as increased acidity, moisture content, or particulate contamination, ensuring optimal performance and longevity of the transformer. Regular maintenance using this machine is crucial for reliable transformer operation.
