DOE published a final rule prescribing new energy conservation standards for distribution transformers. 78 FR (Ap ). The liquid-immersed and medium-voltage dry-type distribution transformers energy conservation standard rulemaking docket EERE––BT–STD– contains all notices, public comments, public meeting.

This standard is intended for use as a basis for determining the energy efficiency performance of the equipment covered and to assist in the proper selection of such equipment. This standard covers single-phase and three-phase dry-type and liquid-filled distribution transformers.

This standard has been rescinded and is no longer for sale on the NEMA website. If needed, please contact Techstreet at ()or () (outside the U.S.) or email [email protected] to inquire about buying historical copies.
