Industry standards that deal with transformer sound and factors affecting sound levels of transformers in field operation are also discussed. Guidelines are provided for the selection of suitable methods of reduction of transformer sound at the design stage, during manufacturing, and on site. Procedures that are typically used for determining required sound levels of power transformers on site are described. The intent is to provide users and manufacturers with sufficient background that can help produce power transformers that meet limits on sound level required by local sound ordinances.IEEE Std C57.136-2023: Guide for Audible Sound of Liquid-Immersed Power TransformersSoundHearingElectric transformersDesign and constructionIEEE StandardsinspectImmersion coolinginspectAcousticsinspectPower transformersinspectSound.Hearing.Electric transformersDesign and construction.IEEE StandardsImmersion coolingAcousticsPower transformers534IEEE Power Engineering Society.Transformers CommitteeNjHacINjHaclDOCUMENT996543347703316C57.136-20233659059UNISA
