Harmonic Mitigating Transformers

  • Harmonic Mitigating (Cancelation) Transformers

Energy efficient transformer represents the next level premium efficiency jump in the dry-type, three-phase ventilated transformer market, since the adoption of TP-1 transformer energy efficiency levels as part of the EPACT 2005 legislation. E3 transformers are the right choice for those looking for lowest energy/heat losses, green/LEED design, and 24 hours a day, 7 days a week energy savings with no additional maintenance to maintain efficiency in today's modern buildings.

  • No additional maintenance is needed, increasing energy efficiency and savings.
  • Reduced heat output helps to reduce cooling costs.
  • Single electrostatic shield for attenuation of common-mode and transverse-mode noise.
  • Low energy losses reduce pollution making it even more environmentally friendly.
  • Increased efficiencies help gain LEED points to document energy savings.
  • Copper windings and terminals are standard for addded resistance to corrosion and enhanced conductivity.
  • Energy savings provides a return on investment energy savings analysis.

      Federal Pacific 600 Volt Class NEMA Premium® 30 Energy Efficient Transformers are designed to exceed present minimum DOE TP-1 efficiency program standards by having at least 30% lower losses beyond the TP-1 rating at a 35% nameplate loading. NEMA Premium® 30 Transformers will allow for LEED® certifications in commercial, industrial and institutional facilities. NEMA Premium® 30 Transformers are essentially equivalent to what is known in the industry as a CL-3 efficiency transformer.


  • Lower operating temperatures
  • Reduced operating costs
  • Size, reliability, and performance similar to standard transformers
