Since the widespread acceptance of AC power, transformers have been a vital part of the electric infrastructure. Transformers are highly resourceful and widespread, whether it’s an industry, a commercial site or the residential sector. The US Department of Energy has laid down some rules and regulations for increasing the energy efficiency of transformers. These rules have been in-effect since January 1st, 2016 and apply to all new transformers being manufactured.
Hammond Transformers have long been supporters of environment-friendly laws, and proudly accepted the new legislation. HPS Distribution Transformers have undergone several redesigns based on customer inputs and the new requirement in place. The new DOE 2016 product lines are highly efficient in terms of electric power output, while making sure they leave little economic footprint.
For starters, upgrading a 75kVA transformer to a new DOE design saves one of the following:
- 2.9 acres of forest per year
- 403 gallons of gasoline
- 3,846 pounds of coal burnt
Hammond has released three lines of low voltage DOE 2016 compliant distribution transformers:
- HPS Sentinel G - Rated for 600 volts and below, suitable for supplying general appliances
- HPS Sentinel K - Designed to handle harmonics generated by non-linear loads like telecommunication equipment
- HPS Sentinel H - Superior to the K series, combine zero sequence flux cancellation with phase shifting to treat 3rd, 5th, 7th, 9th, 15th, 17th and 19th order within the secondary windings.
All three lines are manufactured with material of the highest quality, i.e. non-aging, cold rolled silicon steel laminations. The cores are cut with precision to trap tolerances and improve performance. The copper or aluminum conductors are wound with a high degree of accuracy to maintain the transformer’s life during short-circuit conditions.
The high efficiency of these transformers will ultimately benefit the customer, with:
- Low operating costs and thus increased profits.
- Decreased cost of ownership.
- Lower heat emissions leading to lowered air conditioning costs.
All product lines meet the DOE 10 CFR Part 431 energy efficiency, and are suitable for indoor or outdoor applications through Standard Type 3R enclosures. The design is industry-standard, and the build quality continues to build on the legacy of reliability of all Hammond Transformers.
