Abstract
An improved method and procedure of change-out of a defective power transformer. A replacement transformer is temporarily substituted for the defective transformer which is to be removed. The replacement transformer is brought to the transformer site and placed on a suitable support while the defective transformer is disconnected. The replacement transformer is temporarily electrically connected between the incoming utility lines and customer facility, and the defective transformer is removed. In the event the site has become contaminated by leaking transformer fluid or the like, the site is cleaned up. Then, the replacement transformer or another transformer, is moved to the site and connected in place of the removed defective transformer.
