ENERGY EFFICIENT LOW VOLTAGE DISTRIBUTION TRANSFORMERS
HPS offers three lines of energy efficient low voltage distribution transformers which meet or exceed U.S. DOE 10 CFR Part 431 (and/or TP1) efficiency standards and the Canadian Energy Efficiency Regulations SOR/94-651 (and/or C802.2) efficiencies. For more information on CSA C802.2 minimum efficiency values for dry-type transformers please click here.
Energy Efficient General Purpose Transformers
Energy efficient general purpose low voltage distribution transformers are rated for 600 volts and below. They are generally used for supplying appliance, lighting, heating, motorized machine and power loads from electrical distribution systems. For non-linear loads, all standard energy efficient distribution transformers have to be derated to allow for additional heat due to harmonic losses.
Energy Efficient K-Factor Transformers
Energy efficient k-factor low voltage distribution transformers are rated for 600 volts and below. The use of k-factor distribution transformers has become a popular means of addressing harmonic related overheating problems where electronic ballasts, drives, personal computers, telecommunications equipment, broadcasting equipment and other similar power electronics are found in high concentrations. These non-linear loads generate harmonic currents which can substantially increase transformer losses. The k-rated transformer has a more rugged design intended to prevent failure due to overheating.
Energy Efficient Harmonic Mitigating Transformers
Energy efficient harmonic mitigating low voltage distribution transformers are rated for 600 volts and below. Harmonic mitigating transformers are superior to k-rated and general purpose transformers in that they reduce voltage distortion (flat-topping) and power losses due to current harmonics created by single-phase, non-linear loads such as computer equipment. Secondary windings are arranged to cancel zero sequence fluxes and eliminate primary winding circulation currents. They treat zero sequence harmonics (3rd, 9th and 15th) within the secondary winding and 5th and 7th harmonics upstream with appropriate phase shifting.

Energy Efficient K-Factor Transformers
HPS Synergy® Series
PS Synergy® energy efficient k-factor distribution tranformers are rated for 600 volts and below. K-factor transformers are most frequently used for applications such as commercial or institutional buildings, will, by definition, they supply widely varied single phase loads. Energy Efficient K-Factor transformers are energy efficient general purpose transformers, but are designed to tolerate the harmonics distortion associated with non-linear loads.
HPS provides two lines of energy efficient k-factor transformers:
