Summary

The brochure covers all aspects of audible sound relevant for new power transformer purchases > 3 MVA to be considered in the process from specification until installation. Strict distinction is made between the individual sound level components ‘no-load sound level’, ‘load sound level’ and ‘cooling system sound level’ but the combination of the components is also explained. Key results are provided in easy-to-use graphs. The brochure is also intended to serve as educational document for transformer acoustics.
