This part of GB 1094 defines sound pressure and sound intensity measurement methods by which sound power levels of transformers, reactors and their associated cooling auxiliaries may be determined.
Note: for the purpose of this standard, the term "transformer" means "transformer or reactor".
The methods are applicable to transformers and reactors covered by the GB 1094 series, GB/T 10229, GB 6450 and GB/T 18494 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 trans- formers. Nevertheless, the same general rules as are given in this standard may be followed when on-site measurements are made.
