The criteria, standards, and application guidance
for transformers contained in this advisory will be incorporated
in "TECHNICAL MANUALS" and "CORPS OF ENGINEERS GUIDE
SPECIFICATIONS." These changes are a direct result of a multi-
service meeting on transformer dielectrics and their hazards.
This advisory provides current (criteria,
standards, practices, and policy) requirements for the
TYPE OF PROJECTS.
(1) For new facilities, the following relatively
nonhazardous transformer dielectric materials are permitted on
Bisphenol Epoxy dry.
(2) The application guidance for the three transformer
types (Mineral Oil, High Fire-Point and Dry) are as follows:
Mineral Oil Dielectric Transformers:
The indoor application of mineral oil dielectric filled
transformer will comply with the "National Fire Protection Code,"
National Electrical Code," MIL-HDBK-1008, "Fire Protection For
Facilities Engineering Design and Construction" and the "National
Electrical Safety Code."
