[Boatanchors] Baking moisture from power transformers

[John King via Boatanchors]

I have  a plate power transformer that has been stored inside the shop and not exposed to moisture other than the normal high humidity of the Louisiana climate. I would like to be sure that it has not absorbed sufficient moisture from the inside atmosphere to endanger its' likely of developing a short.

I am considering baking it in my wife's (K5MOL's) kitchen oven. I am interested in your experience with residual moisture removal from stored transformers. I have read somewhere that 150 degrees  might do the job without damaging the insulation. What temperature have you used and for what period of time? Your input based on experience or referral to the information on the internet will be appreciated.  Thanks and 73, John, K5PGW
