IEC 60076-10:2001 pdf free download.Power transformers -Part-40: Determination of sound levels.

This part of lEC 60076 defines sound pressure and sound intensity measurement methods bywhich sound power levels of transformers,

reactors and their associated cooling auxiliariesmay be determined

NOTE For the purpose of this standarc, the term "transformer" means "transformer or reactor".

The methods are applicable to transformers and reactors covered by the lEC 60076 series,IEC 60289,IEC 60726 and the IEC 61378

series,without limitation as regards size or voltageand when fitted with their normal cooling auxiliaries.

This standard is primarily intended to apply to measurements made at the factory.Conditionson-site may be very different because of the proximity of objects, including other trans-formers. Nevertheless, the same general rules as are given in this standard may be followed when on-site measurements are made.
