Abstract


The purpose of this paper is to analyze thebehavior of three-phase distribution transformers whensubmitted to recovery, taking into consideration fixed andvariable electric losses considering the transformer as aconsumer unit to demonstrate the economical feasibility,especially those that do not modify the core. It has been usedroutine tests data obtained from a company that recover foran important power deliver. This paper also deals with thedisposal of the material considering environmental concerns,for a better use of natural resources. It is important tomention the fact that many transformers have alreadyoperated for more than 20 years. The recover allows thedeliver to provide energy to residential or rural low-incomeconsumer through a low investment with the construction ofnew electric power grid.Index Terms ⎯ discard electric losses, transformers reformor recovered, economical feasibility.
