The Energy Policy Act of 2005 (H.R. 6) requires Distribution

Transformers manufactured after January 1, 2007 to meet

speciﬁ c energy efﬁ ciency requirements. EPAct 2005

deﬁ nes the term “distribution transformers” as any

transformer which:

The following special purpose transformers are excluded

from the deﬁ nition of “distribution transformers” and are,

therefore, not required to meet the energy efﬁ ciency stan-

dards at this time:

Benefiting from Higher Energy Efficiencies

Increasing the energy efﬁ ciency of a transformer allows the

unit to operate at the same level of power with less energy

being wasted in the process. Decreasing usage through

reduced waste by just .03% over the next 20 years cuts the

need for new power generation in the United States by 60 to

66 million kw.

SolaHD has been engineering and producing energy

efﬁ cient transformers for the past six years. The SolaHD E

version transformers are optimized to meet NEMA’s TP-1

limits for load losses calculated to 35% of the name plate

rating, yet are the same compact size and footprint as its’

conventional 150˚C rise units.

The example pictured in Figure 1 shows the differences in

efﬁ ciency for the old standard model compared to the

compliant model. At 35% load, the absolute difference in

efﬁ ciency is only 1.7%. However, that represents a 52%

reduction in wasted energy. Taking that 52% reduction in

wasted energy and multiplying it across all the energy

consumed results in substantial savings.

SolaHD offers the following family of transformers that meet

the strict efﬁ ciency standards. The efﬁ ciencies of these trans-

formers are op ti mized for the load losses calculated

at 35% of the name plate rating. This 35% represents an

industry average load of most LVGP trans form ers.

Applications

Any situation where the available voltage must be changed

to accommodate the voltage required by the speciﬁ c

elec tri cal circuit or connected equipment. For many

elec tri cal circuits, the National Electrical Code (NEC)

requires a separately derived neutral secondary connection

provided by Delta-Wye connected transformers.

Distribution transformers can be located close to the load.

No vaults are required for installation and no long, ex pen sive

feeder lines are needed. Common ap pli ca tions include

inductive and re sis tive loads such as motors, lighting and

heating.

General Purpose Transformers

Transformers designed to meet the high energy efﬁ ciencies

required by NEMA Standard TP-1.

Low Temperature Rise Transformers

Transformers designed to limit the temperature rise of the

core and coil assembly to either 80°C or 115°C above a

40°C ambient. Reduction in temperature rise increases

reliability.

K-Factor Transformers

Transformers designed to withstand the electrical anomalies

associated with solid state equipment and DC power

supplies (ex clud ing SCR variable speed motor drives)

without derating the nameplate kVA.

Copper Wound Transformers

SolaHD general purpose transformers have standard

aluminum coil windings. As an option, we offer a selection

with copper windings.
