Date of publication by manufacturer: 2023-11-04
Description
Huawei smart transformer station STS shall be designed and manufactured according to IEC 62271-202, IEC 60076 and IEC 61439 standard. And the noise level of STS shall be fully complied and tested in accordance with IEC 60076-10 “Power transformer – Part 10 Determination of sound levels – Application guide”.
Detailed noise level for each applicable STS is listed in the table below.
Test condition & test method
The STS sound level measurements are carried out at rated output voltage and rated frequency, and immediately after the background measurements, A-weighted sound pressure level measurements are carried out for each measuring position located around the transformer as detailed in the IEC 60076-1.
