Power Transformers Blog – Expert Safety and Usage Info

MIDWEST sometimes finds strange things inside air cooled dry type used transformers we have purchased for reconditioning and resale.  But you can imagine the surprise of our switchgear shop when they removed the top from a “like new” looking transformer enclosure and found “nothing.”  They said it was the fastest used transformer reconditioning job they ever had. It took about three minutes.  Of course they had nothing to show for it but a metal box.  The old transformer core and coil had been removed, leaving only the metal enclosure.  This was a 225 kva transformer, so whoever removed the core and coil used more than the armstrong method.  If you are looking for a reconditioned used invisible dry type air cooled electrical power transformer, cheap freight, low maintenance, no electrical losses, no visible defects, we have a deal for you.  Of course the transformer does not work, but it’s free. The enclosure is extra.
