适用范围

This guideline is valid for transformers with a rated frequency of 50 Hz. The guideline Covers - Transformer group 1; public distribution transformers with rated powers from 50 kVA to 2 500 kVA; - Transformer group 2: medium voltage@ industrial and auxiliary transformers with rated powers greater than 1 MVA; - Transformer group 3; mains and generator transformers with rated powers greater than 10 MVA. The noise emission of abovementioned transformers@ which has been determined using standardized measuring methods (see clause 2)@ is described in this Guide? line by means of the characteristic emission values defined in clause 3 and presented in clause 4. Furthermore@ this Guideline includes notes concerning noise declaration and noise reduction measures (Annex A). This Guideline enables its users@ such as manufacturers and users of transformers@ planners of transformer stations and power plants@ as well as institutions in Charge of assessing@ testing and monitoring noise emission@ to assess transformers from the acoustical point of view.
