PCB

[matanuska11]

Hey, I am trying to find a database of transformers (manufacturer, serial number)that references when their products might of been filled with PCB's and when they discontinued using them. I appreciate the help.

I don't think there is such a database, and even if there was it wouldn't be certain that a transformer supposedly filled with oil wasn't contaminated with PCB. The safest approach is to test the oil. Simple test kits are widely available and inexpensive.

Thanks Marmite-I have some PCB data sheets from over the years that list manufactures use in their products, but it is little to go on with the regulations that are in effect. Appreciate your help.

I believe there was a date of manufacture put out by the Federal Government after which all transformers and oil filled devices had to be PCB free; like 1979 or something like that.

Anything before is suspect and has to be tested when drained, spilled, retrofilled, shipped, etc.. Anything after that date is supposed to have it stamped on the nameplate.

To add, if an item does NOT have PCB info on the nameplate and you don't have any proof (test results, date of manufacture) proving it to be PCB free, then you have to handle as if it's contaminated.
