ENERGY EFFICIENT
TRANSFORMERS
TRANSFORMERS REMAIN A KEY AND ESSENTIAL PART OF OUR
NATION’S ELECTRICAL INFRASTRUCTURE POWERING INDUSTRIAL,
COMMERCIAL AND RESIDENTIAL APPLICATIONS.
The U.S. Department of Energy’s (DOE) new legislation governing the energy efficiency of distribution
transformers went into effect on January 1, 2016. The end result of this new legislation (DOE 10 CFR
P431) was to lower environmental impact and a cost savings derived from decreased energy use.
SolaHD supports this change, and the environmental benefits that will result. We know transformers are
a key part of the U.S. infrastructure. SolaHD has a long tradition as a high quality, U.S. manufacturer of low
voltage general purpose distribution transformers. We are proud to offer transformers manufactured of
unsurpassed quality, right here in the United States. SolaHD’s enclosure sizes did not change for the DOE
2016 energy efficiency transformers. These models fulfill the DOE 2016 requirements utilizing the same
form, fit and function of the pervious TP-1 (EPACT 2005) models.

DOE energy efficient transformers. Custom models are available.

DOE 2016 TRANSFORMERS
A transformer under normal operation is almost always energized, thus making any
energy efficiency improvements more significant over an extended period of time. This
means that customers will be rewarded in two ways:
1.by reducing greenhouse gas emissions and there is an economic payback
through reduced energy costs overtime. Considering the life expectancy
of a transformer and the fact that the transformer will be on 24 hours a
day, 7 days a week for the next 25-30 years, even small energy efficiency
improvements will pay dividends over the life of the transformer.
2.generating less heat translates into lower costs to cool the environment in
which they are utilized equating into more savings not easily identified in
calculations.
GENERAL PURPOSE
LOW TEMPERATURE
K FACTOR
Energy efficient dry-type transformers 600 Volt
Class, isolation type, single phase (15 to 167
kVA) and three phase (15 kVA through 500 kVA).
Indoor and outdoor models available.
SolaHD low temperature rise transformers feature
a 220°C insulation system and temperature rise
of only 80°C or 115°C under full nameplate load.
Reduction in temperature rise increases reliability.
FEATURES
•Energy Efficient Compliant to DOE 2016
•UL Listed/NEMA Type 3R ventilated outdoor
enclosures when used with optional weather
shields (order separately)
•UL Class 220°C insulation system, 150°C
temperature rise under full load
•Terminal board connections and spacious
wiring compartment
•Panel enclosure design reduces labor time.

•High efficiency for low cost operation
•Single and three phase availability
•Fast delivery
•10 year limited warranty
The 35°C thermal reserve on 115°C rise units and
70°C reserve on 80°C rise units definitely mean
higher reliability. The extra benefit is being able
to operate either of these transformers as a 150°C
rise unit and have a short term overload capacity
of 15-30% without compromising normal life
expectancy (See Figure 1 below).
The SolaHD K-Factor design is a specialized
transformer that offers:
•Conductors capable of carrying the harmonic
currents of non-linear loads without exceeding
the temperature rating of the insulation
system.
•A transformer design that takes into account
the increase in naturally occurring “stray”
losses caused by non-linear loads. These losses
cause standard transformers to dramatically
overheat and substantially shorten design life.
•A core and coil design that manages the DC
flux caused by triplen harmonics. As these
harmonics increase, they cause additional
current to circulate in the delta winding. This
produces a DC flux in the core which leads
to core saturation, voltage instability and
overheating.
