Power transformers - Part 10: Determination of sound levels EN 60076-10:2001

Publication date:   Sep 12, 2003

Scope

Defines sound pressure and sound intensity measurement methods by which sound power levels of transformers, reactors and their associated cooling auxiliaries may be determined. The methods are applicable to transformers and reactors covered by the EN 60076 series, EN 60289, EN 60726 and the EN 61378 series, without limitation as regards size or voltage and when fitted with their normal cooling auxiliaries. This standard is primarily intended to apply to measurements made at the factory. Conditions on-site may be very different because of the proximity of objects, including other transformers. Nevertheless, the same general rules as are given in this standard may be followed when on-site measurements are made.
