Consideration of Standards and Recommendations for Selection, Installation and Maintenance of Substation Transformers_Final Draft_021120.docx

This paper will discuss the key applicable North
American Standards defining performance, testing, installation and routine
field maintenance of liquid-immersed distribution substation transformers.
These transformers, typically applied in commercial and industrial power
systems, can be installed either in outdoor or indoor locations, applied as
remote or close-coupled to either primary or secondary switchgear, or both. Recommendations based on these standards for
selection, installation and factory/field testing industry users should specify
to maximize reliability, operational efficiency and safety will follow.
