Could these transformers have PCB oil?
I am eyeing a couple of transformers that come up for auction today:
http://www.bidspotter.com/en-us/auct...5-a45e01297e39 http://www.bidspotter.com/en-us/auct...5-a45e01297e3e Unfortunately, I was not able to see them, but I wonder, 1) What is the likelihood that they are copper wound 2) What is the likelihood that they have PCB oil in them thanks |

I would guess 100% likelihood of PCB in the oil. The cost to dispose of the oil would probably be more than the $ you would get for the copper. Paul |

They look old and ugly, maybe from the 40s There should be a nameplate on it that lists what it's filled with. It probably won't say "PCB." They first used it in transformers in 1929, and the EPA says it was used through 1977. My parents lost their well water due to PCBs in 1976. They had to switch to city water. Here are the other product names for PCBs that EPA lists, which should appear on a label: Abestol, Aroclor, Askarel, Chlophen, Chlorextol, DK, EEC-18, Fenclor, Inerteen, Kennechlor, No-Flamol, Phenoclor, Pyralene, Pyranol, Saf-T-Kuhl, Solvol, Non-Flammable Liquid -- Ed Huntress |

Lots of transformers were refitted with no-PCB coolants, and might have inspection tags to show it. |

The AC branded one has a blue sticker on it that may certify it PCB free, but there's no way to read it. Anyways, you stand to lose far more than you'd gain if they are contaminated. What the nameplates on stuff that old say doesn't even matter. You need to have whats inside them tested by a lab to know what they're filled with and if they are tainted with PCBs. |

They look old and ugly, maybe from the 40s In that case, almost certainly will have PCB's. I'd avoid them like the plague. A good number of years ago, I inhereted a number of PCB filled capacitors. It was the local scrapman that put me wise to the fact that they were labeled as containing PCB's. Before I was allowed to dispose of them I had to enclose each one in a plastic bag and then encapsulate them in concrete inside a lidded polythene drum. An expensive time consuming exercise. -- Best Regards: Baron. |

By the end of the 80s, government pressure had forced the removal of PCB from effectively all electrical apparatus. There were and probably still are companies that specialize in flushing old transformers of PCB down to federal standards. Many old transformers were/are essentially irreplaceable without commissioning custom transformers designed and built from scratch with lead times measuring in years. Two of my factory clients went through this in the 80s. One was a chemical plant with a contract for 200MW and the other a paper mill with a contract for 500MW. Both brought in banks of trailer-mounted transformers to sub while the main ones were flushed and filled with PCB-free oil. If the transformer has been processed then it must contain stickers and a nameplate attesting to that fact. If those are missing the be suspicious. Ultimately an inexpensive oil test will tell you for sure. Assuming you're buying those for scrap value, they look like they'd contain enough copper to make an oil test worthwhile.
