DOE 2016 High Efficiency Transformers P D I & O N Y X P O W E R R E A D Y T O M E E T U S D E PA R T M E N T O F E N E R G Y E F F I C I E N C Y S TA N D A R D S ( D O E 2 0 1 6 ) The US Department of Energy has mandated that effective January 1, 2016; distribution transformers manufactured for the United States must meet the new, more stringent Energy Efficiency Standard (DOE 2016) as part of the Energy Policy and Conservation Act (EPCA). The Energy Act mandates specific types of low voltage dry-type transformers manufactured and sold in the USA to have efficiencies as defined by the 10 CFR Part 431 standard when loaded to 35% of maximum capacity. PDI and ONYX Power supports and embraces this new standard and the positive impact it will have on both the environment and our customers’ operational savings. PDI and ONYX Power are well positioned to be a resource to answer any questions on the DOE 2016 regulation, custom design requirements, and delivery schedule. The following Resource Guide is created to assist in understanding the components of the DOE 2016 standard and its benefits.

DOE Definition of a Distribution Transformer: • • • • • • Has 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 Features a capacity range for dry-type transformers of 15 kVA – 2500 kVA Is either a single- or three-phase transformer The full standard can be found in the Code of Federal Regulations.* Furthermore 10 CFR 431.192 defines “low-voltage dry-type distribution transformer” by the following: • • • • Has an input of 600 volts or less; Is air-cooled and Does not use oil as a coolant Must meet the 10 CFR Part 431 Efficiency levels with a 35% load and a temperature of 75 degrees C. The term “distribution transformer” does not include a transformer that is an: • • • • • • • • • • • • • Autotransformer Drive (isolation) transformer Grounding transformer Machine-tool (control) transformer Non-ventilated transformer Rectifier transformer Regulating transformer Sealed transformer Special-impedance transformer Testing transformer Transformer with tap range of 20% or more Uninterruptable power supply transformer Welding transformer © Smiths Power, 2015.

These regulations require that dry-type transformers sold in Canada meet minimum energy performance levels of the CAN-CSA C802.2-06 standard and report energy efficiency verified performance data to Natural Resources Canada (NRCan). The Canadian regulations also require manufactures to have the efficiency testing verified by an independent testing facility. Transformers that meet the TP-1 efficiency standard also meet the Canadian C802.2 standard. As of January 2015, the Canadian officials have not announced any plans to change the transformer efficiency requirements. We expect they will announce a matching program by the end of 2015 and require transformers sold in Canada to meet the same efficiencies of the DOE. European Commission: The Ecodesign Directive from the European Commission takes effect for transformers in July 2015. The new regulations will apply throughout Europe starting from July 2015; an additional stage with stricter minimum standards is planned for 2021. Exceptions: The directive does not apply to transformers solely designed and implemented for the following purposes: • • • • • • • • • • • • • • • Instrument transformers for supplying measurement devices, meters, relays and similar devices Transformers with low voltage windings for use with rectifiers to deliver direct current Furnace transformers Offshore transformers Transformers for emergency operation (Energy-saving) transformers for supplying trains with power Grounding transformers Transformers mounted on rail vehicles Start-up transformers for switching on three-phase current motors to prevent drops in voltage Test transformers for generating a certain voltage or amperage for testing electrical equipment Welding transformers for arc welding equipment or resistance welding equipment Transformers for deep water applications Transformers for explosion-protected applications in underground mining Medium Voltage (MV) to Medium Voltage interface transformers of up to 5 MVA Large power transformers, if proven that technically achievable alternatives are not available for an application, to fulfill the minimum energy efficiency requirements mandated by the directive. • Large power transformers which serve as an equivalent replacement for existing large power transformers at the same physical location/in the same system, if the replacement is not possible without unreasonable costs in conjunction with the transport and/or installation. © Smiths Power, 2015.

Existing Standards CSL-3 The DOE defined five efficiency standards ranging from CSL-1 to CSL-5. To ensure that transformers sold in the United States meet a minimal efficiency level, EPACT 2005 was put into law. Under this legislation, all transformers must meet CSL-1 efficiency, commonly known as NEMA TP-1 efficiency. TP-1 The current standard which describes the energy efficiency requirements for transformers manufactured from January 1, 2007 until December 31, 2015. NEMA Premium Standard The NEMA Premium Efficiency Transformer Program will help utilities, commercial buildings, and industrial plants incorporate super highefficiency electrical transformers into their operations. NEMA originally set the standard for the efficiency of various types of distribution transformers with the publication of NEMA TP 1-2002 Guide for Determining Energy Efficiency for Distribution Transformers, which was later adopted by the U.S. Department of Energy (DOE) as the national energy-efficiency rule for low-voltage dry-type distribution transformers. The new NEMA Premium Efficiency Transformer designation requires 30 percent fewer losses than existing DOE regulations (10 CFR 431) for lowvoltage dry-type distribution transformers. DOE 2016 standard will supersede CSL-3, TP-1 and NEMA Premium standard.
