This guide is limited to matters particular to PSTs and does not
include matters relating to general requirements for power
transformers covered in existing standards, recommended practices,
or guides.

The terminology, function, application, theory of operation and
protection, and design of PSTs are not covered by existing
transformer standards and guides. The purpose of this document is
to provide guidance to those specifying, designing, and using
PSTs.
