ENERGY EFFICIENCY LEGISLATION FOR DISTRIBUTION TRANSFORMERS

The Impact on Transformers

As the world’s largest energy consumer, the United States uses 3.7 trillion kilo-watt-hours per year of power. Even with the recent surge in energy prices and a greater awareness of the need to protect the environment, this number will continue to increase until consumers and businesses see the benefits of choosing more energy efficient product designs.

Congress, understanding that people can be financially enticed to change behaviors and business practices, created new legislation. According to the legislation, pertaining to low voltage dry-type distribution transformers, the responsibility has been placed on the transformer manufacturers to comply or face civil penalties. This will ensure that all new and replacement transformers will meet the new efficiency requirements by removing the option of using a lower efficiency unit.

Distribution Transformers manufactured after January 1, 2016 shall meet specific energy efficiency requirements. The requirements are based on a specification developed by the National Electrical Manufacturers Association

(NEMA) with assistance from transformer manufacturers and the U.S.

Department of Energy (DOE). DOE’s CFR (Code of Federal Regulations) title 10 part 431 was published in the Federal Register Vol. 78, No. 75, also referred to as DOE 2016.

The term Distribution Transformer is clearly defined in the Federal Rule and specific exclusions are provided for some types of transformers.

The exclusions only apply to designs where compliance would not be economically justifiable or would be technically difficult to accomplish. If in practice some of these exclusions are abused, the law will be modified to prevent such abuse. DOE 2016 defines the term “distribution transformers” as any transformer which:

• Has an input voltage of 34.5 kV or less

• Has an output voltage of 600 V or less

• Is rated for operation at a frequency of 60 Hz

• Has a capacity of 10 kVA to 2500 kVA for liquid-immersed units and 15 kVA to 2500 kVA for dry-type units

The following special purpose transformers are excluded from the definition of “distribution transformers” and are, therefore, not required to meet the energy efficiency standards at this time:

• Autotransformers

• Drive (isolation) transformers

• Grounding transformers

• Machine-tool (control) transformers

• Non-ventilated transformers

• Rectifier transformers

• Regulating transformers

• Sealed transformers

• Special-impedance transformers

• Testing transformers

• Transformer with tap range of 20 percent or more

• Uninterruptible power supply transformers

• Welding transformers

Product lines affected by the new requirements include; Low Voltage

General Purpose (LVGP) transformers (ventilated units only), K-factor, and Low Temperature rise units. Non-compliant designs in these product categories became obsolete effective 12/31/15. Any units produced on or before that date can still be shipped and used by customers. All standard units in SolaHD’s product line which are non-compliant with the new Federal

Rule will be replaced with a new compliant design.

A majority of the units affected are included in this brochure. Custom units affected by the rule will be replaced on a case-by-case basis using the Custom Transformer Quote Request process. While the compliant transformers will add to the cost of construction and maintenance projects, the end user will save this cost over the life of the transformer.

It was a goal of the U.S. Department of Energy (DOE) to improve the energy efficiency of distribution transformers. They have the legal authority to define efficiency levels and enforce compliance. In addition, environmentally conscious consumers and individuals also recognize that buying a higher energy efficiency transformer will have both a financial and environmental impact in the coming years.

The DOE has worked over the last few years to established new and more stringent energy efficiency levels for distribution transformers. The law went into effect January 1, 2016 making these new levels mandatory.

This new law primarily affects three-phase efficiency levels. Single phase levels will remain the same. Please refer to the table on page 5 for the efficiency levels which apply to the low-voltage dry-type transformers that

SolaHD manufactures; these are distribution transformers that include low temperature rise, K-Factor and general purpose. There are additional distribution transformers affected. Those are defined in the DOE’s CFR

(Code of Federal Regulations) title 10, part 431 (also known as DOE 10 CFR p431). It was published in the Federal Register Vol. 78, No. 75.

How SolaHD is Supporting this Legislation and Our Customers.

It is important to note that the mandated energy efficiency levels were hovering around 98-99%, depending on the type of transformer and ratings. This means that any further efficiency improvements become more challenging to achieve. Typically they will require more and/or better core and conductor materials. In most cases, this will directly impact the cost of the transformer. However, there is an economic benefit to offset the higher initial transformer costs overtime. SolaHD has made every effort to optimize our DOE 2016 designs to minimize cost impacts, but expect prices to be higher throughout the transformer industry.

The end result of the new legislation is a lower environmental impact and a cost savings derived from decreased energy use for our customers. SolaHD supports this change, and the environmental benefits our society will receive as a result. 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 that meet the most stringent energy efficiency requirements today, and are in a position that supports the new DOE 2016 higher efficiency designs for our valued partners and customers.

HIGHER ENERGY EFFICIENCIES

The Impact on Hevi-Duty Transformers

Benefiting from Higher Energy Efficiencies

Increasing the energy efficiency of a transformer allows the unit to operate at the same level of power with less energy being wasted in the process. This has a large impact on the consumption and distribution of energy because the reduction in energy usage improves the nation’s energy independence, reduces environmental impacts, lessens infrastructure investment, and protects and strengthens the economy.

Decreasing usage through reduced waste by just .03% over the next 20 years cuts the need for new power generation by 60 to 66 million kw. That drop would eliminate the need for construction of 11 new 400-megawatt power plants by 2038. Electrical power generation accounts for 35% of all

U.S. emissions of carbon dioxide, 75% of sulfur dioxide and 38% of nitrogen oxides. With higher-efficiency transformers, the country will see reduced emissions of CO2, NOx and Hg of 678.8 Mt, 187.7 kt, and 6.48 t over the next 30 years. Curbing energy imports also bolsters the U.S. economy by reducing the current $65 billion trade deficit and mitigating fuel prices through decreased demand.

As your full-range provider of power conversion and power quality related products, SolaHD has been engineering and producing energy efficient transformers to meet the market demands.

Our experienced engineers provide the best performing, most cost-effective designs on the market. The SolaHD transformers are optimized to meet DOE

2016 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.

All units in this brochure meet or exceed the required DOE 2016 efficiency levels. On the surface the absolute change seems insignificant, however the reduction in lost energy is dramatic when you consider that almost all of the energy consumed goes through at least one distribution transformer.

The example pictured in Figure 1 shows the differences in efficiency for the old standard model compared to the compliant model. At 35% load, the absolute difference in efficiency 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.

Some general effects of the legislation:

A transformer under normal operation is always on, 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. They are 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. It will generate less heat. In many cases this translates into lower costs to cool the environment in which they are utilized equating into more savings not easily identified in calculations. (Note: Transformers on average are at 35% loading).

Some effects of the legislation on SolaHD:

• 600 Volt class 60 Hz, dry type general purpose, 3-phase 15-500 kVA

• Losses will be reduced approximately 30%, majority in the core

• Part numbers are

— General Distribution and Low Rise: ET Series will become E Series

i.e. ET2H45S becomes E2H45S

— K-Factor: 3HXXT Series will become KXXE Series

i.e. 3H4T2H15S becomes K4E2H15S

• Enclosure sizes are not changing

• Not affected: Single phase 600 Volt class will remain at EPACT 2005

(previously TP-1) levels and are now referred to as DOE 2016 levels.

SELECTION STEPS

To manually select a transformer:

Find the electrical load requirements.

This information is available from the equipment manufacturer and is typically listed on the nameplate of the equipment.

These are:

1. Load operating voltage.

2. Load frequency (expressed in Hz).

3. Determine load size - usually expressed in kVA, amperage or horsepower.

4. Is the load designed to operate on single phase or three phase power?

Know the supply voltage conditions:

1. Available source voltage.

2. Available source frequency (a transformer will not change frequency. The frequency of the supply voltage and the needed load voltage must be equal).

3. Number of phases on power source.

Determine the transformer kVA rating:

1. If the load is expressed in kVA, select the appropriate transformer from the following selection charts (make sure the selected transformer’s kVA rating is equal to or greater than the required load kVA).

kVA (1Ø) =

Volts x Amps

1000

2. If the load is expressed in amperage, use either the appropriate kVA formula listed below or the appropriate sizing chart on the next page.

kVA (3Ø) =

Volts x Amps x 1.732

1000

3. If the load is expressed in wattage, either utilize the formula below to convert to kVA or refer to the equipment nameplate to obtain amperage requirement.

kVA =

Wattage

(1000 x Power Factor of the load)

4. If the load is a motor and expressed in horsepower, refer to the motor horsepower charts on the next page.

Some sizes may require an optional weather shield (order separately) for outdoor use. kVA

SELECTION STEPS

Special Considerations:

Three things to keep in mind for AC, Motor Horsepower Amperage:

1. Motor horsepower charts are based on 1800 RPM squirrel cage induction motors. If using another type of motor, check running amperage against the chart and adjust as necessary.

2. Increase required transformer kVAby 20% if motors are started more than once per hour.

3. If your motor service factor is greater than 1, proportionally increase full load amperage. (i.e. – if service factor is 1.10, increase full load amperage by

10%).

Are there any special application considerations?

A. For ambient conditions over 40°C, derate the transformer nameplate kVA by 8% for each 10°C above 40°C.

B. For high altitude applications, derate the transformer nameplate kVA by 0.3% for every 330 feet over 3300 feet above sea level. This assures proper transformer convection cooling.

C. Some applications may require a transformer design that limits the BTU output of the unit at full load or a design to withstand and mitigate specific electrical anomalies.

PRIMARY AND SECONDARY OVERCURRENTS

Primary Overcurrent Protection

A transformer has all the same component parts as a motor, and like a motor, exhibits an inrush when energized. This inrush current is dependent upon where in the sine wave the transformer was last turned off in relation to the point of the sinewave you are when you energize the transformer. Although transformer inrush could run up to 30 to 35 times full load current under no load, it typically is the same as a motor, about 6 to 8 times normal running current. For this reason it is important to use a dual element slow blow type fuse, the same type of fuse you would use with a motor. If using a circuit breaker, select a breaker with a time delay, again the same type you would use with a motor. If the time delay is not sufficient, you may experience “nuisance tripping” – a condition where the breaker trips when energizing the transformer but it functions properly after it is re-started.

Secondary Overcurrent Protection

Overcurrent devices are used between the output terminals of the transformer and the load for three reasons:

1. Protect the transformer from load electrical anomalies.

2. Since short circuit current is minimized, a smaller gauge wire may be used between the transformer and the load.

3. Per NEC, a larger primary fuse may be used to reduce nuisance tripping.

LOW TEMPERATURE RISE

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.

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).

Low temperature rise transformers are designed for any critical application requiring extra overload capability and cooler operating temperatures.

All are available with either a 115°C or 80°C thermal rise and a Class 220°C insulation system.

Features

• Energy Efficient Compliant to DOE 2016

• Extra thermal reserve

Accessories and Optional Design Styles

• Energy Efficient Compliant to DOE 2016

• Wall mounting brackets (500 lbs maximum) (Item WB1C)

• Weather Shields (UL Listed/NEMA Type 3R)

K-FACTOR

K-Factor transformers are designed to reduce the heating effects of harmonic currents created by loads like those shown in

Chart A. The K-Factor rating is an index of the transformer’s ability to withstand harmonic content while operating within the temperature limits of its insulating system. SolaHD K-Factor transformers have UL ratings of K-4, K-13, and K-20.

The SolaHD K-Factor design is a specialized transformer that offers these benefits:

• 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.

Features

• Energy Efficient Compliant to DOE 2016

• Conductors to carry harmonics of a K-rated load without exceeding insulation temperature ratings

• UL 1561 Listed up to K-20 rated protection

• Rated temperature rise of 150°C, 220°C insulation

• Shielded for quality power

• Basic design takes “stray losses” into account and functions within safe operating temperatures

• Core and coil design engineered to manage the zero sequence flux caused by triplen harmonics

• Provides 100% rated current without overheating the windings or saturating the core

Accessories and Optional Design Styles

• Wall mounting brackets (500 lbs maximum) (Item WB1C)

• Weather Shields (UL Listed/NEMA Type 3R)

• Totally enclosed non-ventilated designs (TENV) (Non UL) *

• Low temperature rise units available

K-FACTOR

K-Factor transformers are designed to reduce the heating effects of harmonic currents created by loads like those shown in

Chart A. The K-Factor rating is an index of the transformer’s ability to withstand harmonic content while operating within the temperature limits of its insulating system. SolaHD K-Factor transformers have UL ratings of K-4, K-13, and K-20.

SPECIFICATION GUIDE

Low Voltage, General Purpose, Dry Type Transformers (600 Volt Class) - 15 kVA and larger

General

• Single and three phase distribution transformers (600 Volt and below)

• Provide and install, as referenced on the electrical plans, enclosed dry type transformers as manufactured by SolaHD or approved equal.

Standards

• Transformers must be listed by Underwriters Laboratory, certified with

Canadian Standards Association and designed, constructed and rated in accordance with NEMA ST 20 and applicable IEEE & OSHA specifications.

Enclosures

• Transformer enclosures shall be constructed of heavygauge sheet steel and coated with a grey powder paint finish (ANSI 61). Ventilated transformer enclosures shall be UL/NEMA Type 1 rated and UL/NEMA

Type 3R rated for outdoor use with the addition of a weather shield. This information must be listed on the transformer nameplate.

• Maximum transformer enclosure temperature will not exceed 65°C rise above a 40°C ambient under full load.

• Transformers must have vibration isolators located between the core and coil assembly and the transformer enclosure to reduce audible sound levels caused from magnetostriction of the transformer core. No externally located vibration dampening pads shall be used as they tend to increase audible noise. Ventilated transformers are to be floor mounted to aconcrete pad.

• The transformer enclosure must be grounded by the installer in accordance with the latest edition of the National Electric Code and any local codes or ordinances.

Construction — Cores

• All transformer cores shall be constructed of low loss, high quality, electrical grade laminate steel. By design, the flux density is to be kept well below the saturation level to reduce audible sound level and minimize core losses. The core volume shall allow operation at 10%above rated primary voltage at no load without exceeding the temperature rise of the unit.

Construction — Coils

• Coil conductors shall be either aluminum or copper and must be continuous. The entire core and coil assembly shall be impregnated with a thermal setting varnish and cured to reduce hot spots in the coils and seal out moisture. Coils with exposed magnet wire will not be acceptable.

Transformers shall have common core construction.

• All transformers shall incorporate a faraday (electrostatic) shield between primary and secondary windings for the attenuation of voltage spikes, line noise and voltage transients.

• Transformers shall be provided with six 2.5% full capacity taps – two above and four below primary rated voltage.

• General purpose transformers are classified as isolation transformers.

Performance

• Audible sound levels will not exceed limits established in NEMA ST20:

10 to 50 kVA 45 db

51 to 150 kVA 50 db

151 to 300 kVA 55 db

301 to 500 kVA 60 db

• Transformers, 15 kVA to 500 kVA, shall incorporate a UL recognized 220°C insulation system and exhibit a maximum 150°C temperature rise above a maximum ambient of 40°C under full load.

Warranty

• Transformers are warranted against material, performance and workmanship defects for a period of ten (10) years from date of manufacture with the provision for an additional two (2) years.
