About Us

In 1979, WAPDA Authority established a setup “Transformer Reclamation Power Transformer Engineering Service Unit (PTESU) Workshop” at Lahore for attending the faults developed in Power Transformers. In 2001, The workshop was given under the administrative control of Pakistan WAPDA Foundation. PTESU has rendered valuable services to the Power sector of Pakistan which ensured continuity of Power in the country on the one hand and saved huge foreign exchange through repairs /rewinding of the defective transformers on the other hand.

Power Transformer is one of the expensive component of any Power system. The present worldwide financial recession has resulted in unaffordable price escalation of this essential component. It has therefore become imperative to refurbish the in service transformers to prolong their service life and to rewind the defective ones with new Insulation.
