But the GUY who disassembled the transformers is okay, right?
Maybe there's PCBs. Maybe not. If there are PCBs, there might be enough to be detectable. If so, diluted 1-trillion-to-one in a nearby pond might be sufficient to give one fish a headache.
i , first before starting to take apart this transformer contact your Medical insurance company and add on a Cancer Policy for you and the family members for your may need it if you spill any of this liquid at your house or on you. The transformer oil in not cancer causing stuff till it is used over a year or so and then it become PCB . the stuff is activated by the electricity going through it and become a Cancer causing stuff after they have been used. Now here is a chance to get rid of a unwanted Brother in law or kind folks by just getting them to take it apart and get the oil on them. In Short order your in the class of getting cancer soon.
So if you interested in keeping your family safe and not have cancer. You need to have it hauled off to the Power company work station and dump it out when they are not looking and they have the means to dispose of it properly. There maybe $30 or $40 of copper in it but having Cancer will wipe out that profit real fast.
I've heard OLD veteran teachers say they think there's something in the water - people no longer have reading comprehension skills. Luckily, you and two others here seem to escaped this fate.
You believe he stated that? Go back & read it again. For those of us not familiar with transformers in general, there is no clue as to whether it contained liquid. But never mind. You may *think* it's a problem that I suggested he proceed with caution, but in fact, it was *not* a problem. You just needed to be heard.
Actually, I'd like to know WHO the guy was, not how he is. Please provide a way of contacting him, since you seem to be privy to all the information surrounding this event.
"Unfortunately, Japan's PCB history is tinged with tragedy. In 1968, an accidental mixing of PCB with rice oil affected 14,000 people and resulted in 300 deaths."
Great question. First of all, everything in my house is already on UPSes. From a previous deal where I bought a $45 lot of 28 APC UPSes, bought new batteries, and made $2,500 profit. I have a few more UPSes languishing in my garage, waiting to be used.
As for the latest UPS, I bought a military surplus lot for $80:
Clary OnGuard 3 phase UPS about 250 lbs.
Clary OnGuard 1 phase UPS about 250 lbs
Ferrups 3 kVa UPS about 200 lbs without batteries
Several garbage typewriters and one new in box typewriter
8kVa mystery UPS without front panel, with a battery bank. It is not repairable without the front panel. I now think that it is not Ferrups. It is a 500 lbs monster.
A big badass Canon color copier, about 200 lbs.
That item 5 is what I am demolishing. I may be able to sell the 250V battery bank to some homepower types. No batteries though. I do not think that I can sell the UPS proper. So I am taking it apart in order to, first, be able to handle it without risk of injury, second to get useful screws and wires etc, and third to sell good parts like isolation transformer or capacitors.
Ok, you seem to have made the right decision. I am trying to remember what the transformer looks like. Is it a toroid or a regular rectangular shape. I think the transformer on my big unit is a toroid. I don't know what the core material is. Could be ferrite. I know there was a bunch of tapped windings.
Are you in an area where you could throw it on a trash fire and burn out all the insulation. Then you could see what is there. I used to do this when I lived in Portland, OR and had a wood furnace. Still have some BIG copper strap from a burned out transformer.
The 'm' is a leftover from the olden days, when it meant 'micro', not the metric standard 'milli'. Milli is not used in capacitor rating. Pico, micro then Farads. New capacitors would be probably marked with the 'u' instead of 'm'
YOU just needed to read his original post. He stated it pretty clear he was looking at laminations and windings and paper. If it even remotely was a oil filled transformer, it was a little late for that.
