Acoustic Imaging and its Application in Transformers

The noise generated by transformer operation has always been one of the hotspots in the field of transformers. With the development of society, noise control has received more and more attention, in addition, the position of transformer noise source based on acoustic imaging technology has become more and more important. This paper introduces the basic theory of beamforming, compares the imaging effects of different microphone arrays, and introduces the application of acoustic imaging technology in transformers.
