Rethink distribution transformer efficiency standards; power groups urge Energy Department

Three major power trade groups urged the Department of Energy (DOE) in a Feb. 15 letter to reconsider proposed energy efficiency conservation templates for distribution transformator, citing "serious and ongoing supply chain challenges that are hampering the production and availability of distribution transformers." Extend and complicate.

Substantial proposal amid shortage of transformers

The U.S. Department of Energy'sEnergy's 448-page proposed rule aims to reduce losses in three types of distribution transformers — liquid-immersed, low-voltage dry (LVDT) and medium-voltage dry (MVDT) distribution — through specific percentage-based efficiency standards. Transformer. The proposed standards would apply to distribution transformer units manufactured in or imported into the United States starting in 2027, three years after the rule is finalized, possibly in 2024.

Power companies usually purchase medium-voltage liquid-immersed distribution transformers. Consumers of low- and medium-voltage dry-type distribution transformers are typically commercial and industrial entities.

Currently, NEMA calculates that a three-phase liquid-immersed distribution transformer with a kilovolt ampere (kVA) rated output of 2,500 has an efficiency of 99.53%; a similar single-phase pattern with a kVA of 833 has an efficiency of 99.55%," they said. "Important. Unfortunately, because of the intricacies of how transformers are designed and assembled, improving their efficiency by even a fraction of a percentage point can add months to an already lengthy order cycle.
