With people’s attention to environmental protection

in recent years

the noise of filter capacitor in converter station has been paid more and more attention. Nowadays

there are two standards for noise test of power capacitor in China

they are: GB/T28543-2012 noise measurement of power capacitors and GB/T32524-2016 acoustics-determination of sound power level and directivity character of power capacitor unit using sound pressure

which have some differences about location of measure points and selection of measure facets. This paper uses a theoretical analysis and experimental verification method to study

hoping to give a more reasonable method of noise test for power capacitors for institution and supplier to refer.
