EPMS 2010 LTD recently successfully removed a 1.5 MVA Transformer from a large steel making facility at TATA Steel and returned it to our Birmingham works for a complete strip down and refurbishment
Oil was drained from transformer, radiators removed, windings were then de tanked . Then the transformer was mechanically and electrically checked.
The tanks were originally leaking and badly rusted in several place especially at the bottom and around the base .We removed the existing base and re fabricated a new base. Then repaired other areas of concern around the radiators and fixing points. The Transformers had all gaskets replaced, and then HV and LV boxes were cleaned and prepared for new cabling, The Transformer was then re assembled and filled with oil.
Finally it was painted with primer and top gloss and then delivered back to the Customer; awaiting installation.
