The transformers are the successful result of an intensive research and development effort over a number of years by a team of ABB engineers and scientists in the United States, Sweden, and Germany. Included in the team were experts in the fields of vibrations as well as sound generation, transmission, and radiation. The project also involved the development of appropriate measuring methods of ultra-low-noise levels at discrete frequency components, as well as appropriate transformer mounting. The newly-developed technology has set new industry benchmarks for transformer noise emissions.
