Finding the Right Transformer Core Manufacturer

By |September 30th, 2020|News|0 Comments

How do you select the right transformer core? The single most important factor that buyers should consider before purchasing their core is core efficiency. While the sticker price is an important consideration, core efficiency allows proper assessment of the cost/value proposition. Savvy buyers know to consider life-time costs, rather than solely focusing on the [...]

Efficiency Benefits of DG Wound Cores

By |January 22nd, 2020|News|0 Comments

In the 1938 edition of Transactions of the American Institute of Electrical Engineers, the journal reported on a “radically” new transformer core with a “simple structure and highly efficient performance.” The article boasted that this new core “eliminates or minimizes most of the objections inherent in other [cores].” Today, wound cores continue to set impressive standards [...]

Wound Cores and the Benefits of Annealing

By |March 25th, 2016|News|0 Comments

The magnetic permeability properties of electrical steels are especially sensitive to mechanical stress. During the manufacturing processes required to form a core, steel is subjected to stresses, grain structure is damaged, and the core loss increases. For wound or formed cores, where there is a substantial amount of both plastic and elastic strain, the [...]

Why Corefficient: New DOE Regulations and the Electric Transformer Industry

By |February 23rd, 2016|News, Press Releases|0 Comments

There is a new challenge for the Transformer Industry in 2016: The US Department of Energy (DOE) has determined that higher transformer energy efficiency standards will result in significant conservation of energy. With new amendments to existing standards, electrical losses are expected to drop by about 8 percent for liquid-immersed transformers, 13 percent for [...]
