[Docket No. EE-TP-98-550]
RIN 1904-AA85
Energy Conservation Program: Test Procedures for Distribution
Transformers; Correction
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Final rule; technical corrections.
-----------------------------------------------------------------------
SUMMARY: The Department of Energy (DOE or the Department) published a
final rule on April 27, 2006, amending Part 431 to prescribe test
procedures and other provisions for distribution transformers, pursuant
to sections 323(b)(10) and 346(a) of the Energy Policy and Conservation
Act, as amended. (42 U.S.C. 6293(b)(10) and 6317(a)) This document
corrects three typographical errors in the final rule.
DATES: This correction is effective October 16, 2006.

SUPPLEMENTARY INFORMATION: The final rule that is the subject of this
correction document established (1) Test procedures for measuring the
energy efficiency of distribution transformers, (2) definitions to
delineate the products covered by the test procedures, (3) provisions
manufacturers must use to implement the test procedures, (4)
calculation methods for determining the efficiency of distribution
transformers, and (5) enforcement provisions for this equipment. 71 FR
24971 (April 27, 2006).
Need for Corrections
As published in the final rule, the definition for the term
``excitation current'' which can also be referred to as ``no-load
current'' contains a typographical error that may prove to be
misleading, and needs to be corrected. In the final rule, the
conjunction ``or'' appearing between the terms ``excitation current''
and ``no-load current'' was italicized, such that the two terms
excitation current and no-load current appeared as one continuous
phrase (i.e., excitation current or no-load current). The Department is
concerned that the italicization of the word ``or'' may lead to
confusion about the defined term. This technical correction document
removes the italicization of the word ``or.'' The remainder of the
definition (i.e., ``means the current that flows in any winding used to
excite the transformer when all other windings are open-circuited'')
was correct in the final rule and is not amended by this technical
correction.
In a comment submitted after the publication of the final rule,
NEMA brought to the Department's attention two typographical errors
that have an impact on the calculation of distribution transformer
efficiency and must be corrected. (NEMA, No. 61 at p. 1) In the final
rule notice, Equation 5-1 was given as:
[GRAPHIC] [TIFF OMITTED] TR16OC06.009
And an explanation of one of the terms in equation 5-1, Pos,
was given as follows:
Pos is the specified energy efficiency load level,
where, Pos = PorL2, and
NEMA determined that there are typographical errors in both
equation 5-1 and the explanation of the term Pos. The
Department carefully reviewed this comment, and agrees with NEMA's
determination. In equation 5-1, the quantity contained in the square
brackets should be squared (i.e., raised to the second power). In the
explanation of the term Pos, the variable represented by the
letter ``L'' should not be squared. These errors were present in the
Department's previous supplemental notice of proposed rulemaking for
this test procedure (69 FR 45532), but were not identified at that
time.
Today's technical correction document amends equation 5-1, raising
the contents of the square brackets to the second power, so the
corrected equation reads as follows:
[GRAPHIC] [TIFF OMITTED] TR16OC06.010
Similarly, this technical correction document amends the
explanation of the term Pos to remove the square from the
variable L, so the corrected equation reads as follows:
Pos is the specified energy efficiency load level, where
Pos = PorL, and
