Power Transformer Dryout
Power Transformer Dryout
(OP)
I need to dry out an old transformer and extend the life. Test indicate moisture/contamination in the windings. We have a trailer mounted purifier/vacuum rig. I am not sure that our procedure is adequate. Does anyone have a proven procedure to dryout a transformer using a trailer mounted vacuum/purifier rig?

Contact the manufacture of the vacuum/purifier rig and see what they says about drying out transformers.
Also contact the transformer manufacture, they may have some instructions on drying out the transformer.
Drying out a high voltage transformer is a complicated process and if you have no experience, I would recommend contacting a company that specalize in drying out/re-conditing transformers.
Somewhere I have a Westinghouse manual on oil filling their high voltage transformers. If you think it would be helpful, will try and locate it.
Good Luck
