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. Decreasing usage through reduced waste by just .03% over the next 20 years cuts the need for new power generation in the United States by 60 to 66 million kw.
SolaHD has been engineering and producing energy efficient transformers for the past six years. The SolaHD E version transformers are optimized to meet NEMA’s TP-1 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.
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. |
