Sandia National Labs gets funding to develop advanced transformer materials

USA, New Mexico: Sandia National Laboratories has been awarded federal funding of $1.2 million for its Transformers for a Modernized Grid project, as part of the U.S. Department of Energy $98 million program to support some of the top research and development teams working to transform the nation’s energy system.

Sandia will use the funds to develop advanced core materials for grid-level power transformers with the aim of improving efficiency and resiliency, according to the project description.

Current transformers use copper windings surrounding a magnetic core to amplify the magnetic field generated by the coil. With new materials, scientists want to increase electrical efficiency while shrinking the size of the transformers by about 50 percent.

Sandia researchers also will work on developing a new polymer additive for transformer oil.
